The multiples of numbers calculator will find 100 multiples of a positive integer. For example, the multiples of 3 are calculated 3x1, 3x2, 3x3, 3x4, 3x5, etc., which equal 3, 6, 9, 12, 15, etc. You can designate a minimum value to generate multiples greater than a number. For example, to find 100 multiples of 36 that are greater than 1000 you will get: 1008, 1044, 1080, 1116, 1152, 1188, 1224, 1260, 1296, 1332, 1368, 1404, etc. Here is a list of the first 20 multiples of the integers 1 through 20.

Common multiples of 8 and 20 are numbers that both 8 and 20 can be divided into evenly with no remainder. To find the common multiples of 8 and 20, we compare the list of multiples of 8 with the list of multiples of 20 to see what they have in common. To create a list of multiples of 8, we multiply 8 by 1, 8 by 2, and so on like this: 8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 ... Similarly, to create a list of multiples of 20, we multiply 20 by 1, 20 by 2, and so on like this: 20 x 1 = 20 20 x 2 = 40 20 x 3 = 60 20 x 4 = 80 ... When we compare the two lists to see what they have in common, we get the answer to "What are the common multiples of 8 and 20?" 40, 80, 120, 160, etc. Since 40 is the first number they have in common, 40 is the least common multiple of 8 and 20. Note: Our lists are shortened because they go on forever, but can you see the pattern when you look at the answer in green above? The common multiples are in intervals of 40 (the least common multiple), so you can continue the green list above with more common multiples of 8 and 20 by simply adding 40 to the last number on the list.Common Multiples Calculator Need another answer?

It is a sequence where the difference between each next number and the preceding number, i.e. two consecutive results, is 8. Multiples are the numbers that give products of any number multiplied by other natural numbers. There is a difference between factors and multiples, which you can learn here. However, 8 is a factor of 8, and also 8 is a multiple of 8. What are Multiples of 8?The multiples of 8 are the numbers that are generated when 8 is multiplied by any natural number. That means any number that can be expressed in the form of 8n where n is an integer is a multiple of 8. As we know, if two values, p and q, are there, we say that q is a multiple of p if q = np for some integer n. Some of the multiples of 8 include the following. 8, 16, 24, 32,….., 72, 80, 88,…. Thus, as per the definition given above, the multiple of 8 is obtained by multiplying some integer with 8. For example, 48, 56, 64 and 96 are all multiples of 8 for the following reasons.
We can also find the multiples through the repeated addition of a number as many times as required. For example, the first five multiples of 8 can be written as: 8 × 1 = 8 8 × 2 = 16 or 8 + 8 = 16 {here 8 is added for twice} 8 × 3 = 24 or 8 + 8 + 8 = 24 {here 8 is added for thrice} 8 × 4 = 32 or 8 + 8 + 8 + 8 = 32 8 × 5 = 40 or 8 + 8 + 8 + 8 + 8 = 40 Similarly, we write several multiples of the given numbers. What is the 5th multiple of 8?To get the fifth multiple of 8, we have to multiply 8 by 5 or add the number five times. Therefore, the fifth multiple of 8 is 8 x 5 = 40 or 8 + 8 + 8 + 8 + 8 = 40. Multiples of 8 ChartGo through the table given below to get the first 20 multiples of 8 along with the multiplication notation in each case.
From the above table, we can say that the multiples of the number 8 are the results in the multiplication table of 8, as both are the same.

The first six multiples of 8 are 8, 16, 24, 32, 40 and 48. These can be expressed as: 8 × 1 = 8 8 × 2 = 16 8 × 3 = 24 8 × 4 = 32 8 × 5 = 40 8 × 6 = 48 The factors of 8 are 1, 2, 4, and 8. To find the multiples of a number, multiply the given number by other numbers. That means, if two values, p and q, are there, we say that q is a multiple of p if q = np for some integer n. The number which is exactly divisible by 12 is a multiple of12t. Such numbers are 12, 24, 36, 48, 60, 72,… The multiples of 8 until 100 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96. |
