LCM of 10, 15, and 20 is the smallest number among all common multiples of 10, 15, and 20. The first few multiples of 10, 15, and 20 are (10, 20, 30, 40, 50 . . .), (15, 30, 45, 60, 75 . . .), and (20, 40, 60, 80, 100 . . .)
What are the multiples of 20 and 15?
The LCM of 15 and 20 is 60. To find the LCM (least common multiple) of 15 and 20, we need to find the multiples of 15 and 20 (multiples of 15 = 15, 30, 45, 60; multiples of 20 = 20, 40, 60, 80) and choose the smallest multiple that is exactly divisible by 15 and 20, i.e., 60.
Which is the 15th multiple of the number 20?
The 15th multiple of 20 is 20 x 15 = 300. This list of multiples is never-ending, we can generate infinite multiples of 20. The multiples of 20 are also the multiples of its factors. The factors of 20 are 1, 2, 4, 5, 10 and 20. 40 is the 2nd multiple of 20. 40 is also a multiple of 2, 4, 5, 10 and 20.
How are multiples of 15 different from factors of 15?
All numbers which can be divided or the product of 15 is a multiple of 15. The multiples are different from the factors of 15. The factors are the numbers which when multiplied in a pair gives the original number such as 3 x 5 = 15, so here 3 and 5 are not the multiples but the factors.
How to calculate the least common multiple of 15 and 20?
The formula of LCM is LCM (a,b) = ( a × b) / GCF (a,b). We need to calculate greatest common factor 15 and 20, than apply into the LCM equation. Least common multiple can be found by multiplying the highest exponent prime factors of 15 and 20. First we will calculate the prime factors of 15 and 20. Prime factors of 15 are 3, 5.
What are the first five multiples of 20?
The first five multiples of 20 are 20, 40, 60, 80 and 100. What 2 numbers give a multiple of 20? Any number multiplied by 20 gives a multiple of 20. For example, 20 × 5 = 100 and it is a multiple of 20.
