Question

Whats the LCM of 40 and 5

Answer 1

Answer:

The LCM of 40 and 5 is simply 40.

Step-by-step explanation:

To find the lowest common multiple of any 2 numbers, we will first list the prime factors of each number.

40: 2 × 2 × 2 × 5

5: 5

Then we need to multiply each factor the most amount of times it appears in either number.

2: 3 times in the first number

5: 1 time in either number

Now we multiply these.

2 × 2 × 2 × 5 = 40

The LCM of 40 and 5 is simply 40.
