Question

What is the lowest common multiple of 1200, 240 and 600?

Answer 1

The numbers are 1200, 240 and 600.

Write the prime factorization of each number.

1200 = 2 * 2 * 2 * 2 * 3 * 5 * 5 = 2⁴ * 3 * 5²

240 =  2 * 2 * 2 * 2 * 3 * 5 = 2⁴ * 3 * 5

600 =  2 * 2 * 2 * 3 * 5 * 5 = 2³ * 3 * 5².

Multiply highest power of  each factor in the either number.

Least common multiple =  2⁴ * 3 * 5²

= 16 * 3 * 25

= 1200.

Least common multiple of 1200, 240 and 600 is 1200.
