What are the multiples of 8 12 and 15?
Step 2: The common multiples from the multiples of 8, 12, and 15 are 120, 240, . . . Step 3: The smallest common multiple of 8, 12, and 15 is 120.
How to get the least common multiple of 15 and 8?
To get the Least Common Multiple (LCM) of 15 and 8 we need to factor each value first and then we choose all the factors which appear in any column and multiply them: The Least Common Multiple (LCM) is: 2 x 2 x 2 x 3 x 5 = 120 You can always share this solution
Are there any numbers that are multiples of 15?
So, basically multiples are n-times of any number, where n is the list of natural numbers. Thus, number 5 has multiples in the form of 15n, such that: and so on. 615,630,645,660,675,690,705,720,735, … All numbers which can be divided or is a product of 15 is a multiple of 15. The multiples are different from the factors of 15.
How to find the sum of first 15 multiples of 8?
Multiples of 8 are 8, 16, 24,…. Since difference is same, it is an AP We need to find sum of first 15 multiples We use formula Sn = �2 (2?+ (?−1)?) Here, n = 15, a = 8 & d = 16 – 8 = 8 Putting values in formula Sn = ?/2 (2?+ (?−1)?) = 15/2 (2×8+ (15−1)×8) = 15/2 (16+14×8) = 15/2 (16+112) = 15/2×128 = 960 Therefore.
Which is the correct number of multiples of 8?
Multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 168, 176, 184, 192, 200, 208, 216, 224, 232, 240, 248, 256, 264, 272, 280, 288, 296, 304, 312, 320, 328, 336, 344, 352, 360, 368, 376, 384, 392
