# How do you find the Least common multiple of #10, 4, 18#?

Divide the three numbers by three:

The product of all prime factors found in at least one number, taken once with the highest exponent, yields the least common multiple:

To find the least common multiple (LCM) of 10, 4, and 18, you first need to factor each number into its prime factors:

10 = 2 * 5 4 = 2^2 18 = 2 * 3^2

Then, take the highest power of each prime factor that appears in any of the numbers:

2^2 * 3^2 * 5 = 4 * 9 * 5 = 180

Therefore, the least common multiple of 10, 4, and 18 is 180.
