Question

find the least common multiple of the following numbers a 10&15 b 8,5&10​

Answer 1

Answer:

a= 30

b= 40

(a)factors of 10 are= 2 x 5

factors of 15 are= 3 x 5

so the lcm is= 2 x 3 x 5= 30

(b)factors of 8 are= 2 x 2 x 2

factors of 5 are= 5

factors of 10 are= 2 x 5

so the lcm is = 2 x 2 x 2 x 5=40
