What is the LCM of 13 and 14 and 15?

Answer 1

To find the Least Common Multiple (LCM) of three numbers, you first need to find the LCM of two of the numbers, and then find the LCM of that result with the third number.

The LCM of 13 and 14 is 182, as they share no common factors.

Then, finding the LCM of 182 and 15, the LCM is 2730, as 182 and 15 share no common factors either.

Therefore, the LCM of 13, 14, and 15 is 2730.

Answer 2

15 = 3 x 5; 14 = 2 x 7 and 13 is prime. There are no common factors, so LCM is the product of all factors ie 3 x 5 x 2 x 7 x 13 = 2730

Answer 3

2730
