What is the LCM of 42 70 and 112?

Answer 1

To find the Least Common Multiple (LCM) of 42, 70, and 112, we first need to find the prime factorization of each number.

42 = 2 * 3 * 7 70 = 2 * 5 * 7 112 = 2^4 * 7

Next, we take the highest power of each prime factor that appears in any of the numbers: 2^4 * 3 * 5 * 7 = 840.

Therefore, the LCM of 42, 70, and 112 is 840.
