Question

What is the lcm of 4 and 5

Answer 1

Answer:

20

Step-by-step explanation:

4 * 1 = 4        5 * 1 = 5

4 * 2 = 8        5 * 2 = 10

4* 3 = 12        5 * 3 = 15

4 * 4 = 16       5 * 4 = 20

4 * 5 = 20

they both go into 20 equally. there is no number lower than 20 that they both go into
