Identify the Prime Factors of 4, 5 and 9 by Prime Factorization:
Prime Factorization of 4: 4 = 2 x 2 = 22
Prime Factorization of 5: 5 = 51
Prime Factorization of 9: 9 = 3 x 3 = 32
Prime Factors of 4, 5 and 9: 2, 3 and 5
Least Common Multiple of 4, 5 and 9 is the product of their Prime Factors raised to the highest occurrence (largest exponent) of each factor:
LCM(4,5,9) = 22 x 32 x 51
LCM(4,5,9) = 4 x 9 x 5
LCM(4,5,9) = 180
Least Common Multiple of 4, 5 and 9 by Prime Factorization
The solution above and all other related solutions were provided by the Least Common Multiple by Prime Factorization Application.
