Match the two numbers with their least common multiple (lcm).

10 and 4 a) 30

10 and 6 b) 40

10 and 8 c) 20

which ones match the answers?

Step-by-step explanation:

We have to find the LCM of the given numbers and match then with their options given.

LCM of 10 and 4

factors of 10 = 2 × 5

factors of 4 =  2 × 2

LCM = 2 × 5 × 2 = 20         Matches (C)

LCM of 10 and 6

factors of 10 = 2 × 5

factors of 6  = 2 × 3

LCM = 2 × 3 × 5 = 30           Matches (A)

LCM of 10 and 8

factors of 10 = 2 × 5

factors of 8 = 2 × 2 × 2

LCM = 2 × 5 × 2 × 2 = 40      Matches (B)
