Given Numbers: 28, 63, 70
Identify the Prime Factors of 28, 63 and 70 by Prime Factorization:
Prime Factorization of 28: 28 = 2 x 2 x 7 = 22 x 71
Prime Factorization of 63: 63 = 3 x 3 x 7 = 32 x 71
Prime Factorization of 70: 70 = 2 x 5 x 7 = 21 x 51 x 71
Prime Factors of 28, 63 and 70 (collectively): 2, 3, 5 and 7
Least Common Multiple of 28, 63 and 70 is the product of their Prime Factors raised to the highest occurrence (largest exponent) of each factor:
LCM(28, 63, 70) = 22 x 32 x 51 x 71
LCM(28, 63, 70) = 4 x 9 x 5 x 7
LCM(28, 63, 70) = 1,260
Least Common Multiple of 28, 63 and 70 by Prime Factorization
The solution above and all other related solutions were provided by the Least Common Multiple by Prime Factorization Application.
