Question

Two numbers have prime factorizations of 2 2 · 3 · 5 and 2 · 3 2 · 7.

Which expression can be used to find their least common multiple?

Answer 1

Is this correct?

22 * 3 * 5
2 * 32 * 7

Answer 2

I believe you mean that the first one is \[2^2\cdot3\cdot5\] and the second is \[2\cdot 3^2 \cdot 7\] In which case, the least common multiple is found by taking the max power of each term. Thus, the lcm is \[2^2 \cdot 3^2 \cdot 5 \cdot 7 = 1260\]
