example
LCM of 16 24
Prime factorization
16 2 x 2 x 2 x 2
24 2 x 2 x 2 x 3
take all of the unique factors from each pair ONCE (red) 2 x 2 x 2 x 2 x 3 = 48 = lcm
Here is the same thing stated slightly differently:
Find the least common multiple:
lcm(16, 24)
Find the prime factorization of each integer:
The prime factorization of 16 is:
16 = 2^4
The prime factorization of 24 is:
24 = 2^3×3
Find the largest power of each prime factor.
The largest power of 2 that appears in the prime factorizations is 2^4.
The largest power of 3 that appears in the prime factorizations is 3^1.
Therefore lcm(16, 24) = 2^4×3^1:
Answer: |lcm(16, 24) = 48
