Given Numbers: 13, 15, 20
Identify the Prime Factors of 13, 15 and 20 by Prime Factorization:
Prime Factorization of 13: 13 = 131 (prime number)
Prime Factorization of 15: 15 = 3 x 5 = 31 x 51
Prime Factorization of 20: 20 = 2 x 2 x 5 = 22 x 51
Prime Factors of 13, 15 and 20 (collectively): 2, 3, 5 and 13
Least Common Multiple of 13, 15 and 20 is the product of their Prime Factors raised to the highest occurrence (largest exponent) of each factor:
LCM(13, 15, 20) = 22 x 31 x 51 x 131
LCM(13, 15, 20) = 4 x 3 x 5 x 13
LCM(13, 15, 20) = 780
Least Common Multiple of 13, 15 and 20 by Prime Factorization
The solution above and all other related solutions were provided by the Least Common Multiple by Prime Factorization Application.
