What is the Lowest common multiple of 3 8 and 10?

Answer 1

For problems of this kind firstly obtain the prime factors of each number.

3 = 3

8 = 2 x 2 x 2 = 2³

10 = 2 x 5

The Lowest Common Multiple is the product of the highestpower of each prime factor.

The LCM is thus 3 x 2³ x 5 = 3 x 8 x 5 = 120
