Question

What is the Lcm of 7,14,28,35

Answer 1

Answer:

140

Step-by-step explanation:

Any multiple of 14 is also a multiple of 7, so we can disregard the 7.

Any multiple of 28 is also a multiple of 14, so we can disregard the 14.

So we just need the LCM of 28 and 35.

28 = 2 × 2 × 7

35 = 5 × 7

The LCM is then 2 × 2 × 5 × 7 = 140.

Hope this helps.
