Least Common Multiple of 21, 28 and 32 by Prime Factorization

Given Numbers: 21, 28, 32
Identify the Prime Factors of 21, 28 and 32 by Prime Factorization:
Prime Factorization of 21: 21 = 3 x 7 = 31 x 71
Prime Factorization of 28: 28 = 2 x 2 x 7 = 22 x 71
Prime Factorization of 32: 32 = 2 x 2 x 2 x 2 x 2 = 25
Prime Factors of 21, 28 and 32 (collectively): 2, 3 and 7
Least Common Multiple of 21, 28 and 32 is the product of their Prime Factors raised to the highest occurrence (largest exponent) of each factor:
LCM(21, 28, 32) = 25 x 31 x 71
LCM(21, 28, 32) = 32 x 3 x 7
LCM(21, 28, 32) = 672
