Question

Find the least common multiple of each set of numbers.

10 and 45

Answer 1

The answer is 90

5 was the lowest that could go into both numbers so you divide both 10 & 45 by 5 and they will be reduced to 2 & 9. The lowest number that can go again is 2 which will take out the 2 from the 10 leaving it to 1. For the 9 we used 9 to take it out after all this the numbers that were used to divide the given sets of numbers will be multiplied together to get the LCM of the numbers 10 & 45

Answer 2

90

Explanation:

we need to find the multiples of 10 and 45 (multiples of 10 = 10, 20, 30, 40 . . . . 90; multiples of 45 = 45, 90, 135, 180) and choose the smallest multiple that is exactly divisible by 10 and 45, i.e., 90
