Given Numbers: 28, 40
Identify the Prime Factors of 28 and 40 by Prime Factorization:
Prime Factorization of 28: 28 = 2 x 2 x 7 = 22 x 71
Prime Factorization of 40: 40 = 2 x 2 x 2 x 5 = 23 x 51
Prime Factors of 28 and 40 (collectively): 2, 5 and 7
Least Common Multiple of 28 and 40 is the product of their Prime Factors raised to the highest occurrence (largest exponent) of each factor:
LCM(28, 40) = 23 x 51 x 71
LCM(28, 40) = 8 x 5 x 7
LCM(28, 40) = 280
Least Common Multiple of 28 and 40 by Prime Factorization
