Question

What is the lcm of 2 4 5 6

Answer 1

Multiples of 2
2, 4, 6, 8, ... 56, 58, 60

Multiples of 4
4, 8, 12, 16, ... 52, 56, 60

Multiples of 5
5, 10, 15, 20, ... 50, 55, 60

Multiples of 6
6, 12, 18, 24, ... 48, 54, 60

60 is the least common multiple (LCM) of 2, 4, 5, and 6.

Answer 2

Since 2 and 5 are primes, we can find the lcm of 4, 6, and 10 (2 x 5 = 10)

Multiples of 10: 10, 20, 30, 40, 50, 60

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60

So the LCM of 2, 4, 5, and 6 is 60
