Identify the Prime Factors of 9 and 10 by Prime Factorization:
Prime Factorization of 9: 9 = 3 x 3 = 32
Prime Factorization of 10: 10 = 2 x 5 = 21 x 51
Prime Factors of 9 and 10: 2, 3 and 5
Least Common Multiple of 9 and 10 is the product of their Prime Factors raised to the highest occurrence (largest exponent) of each factor:
LCM(9,10) = 21 x 32 x 51
LCM(9,10) = 2 x 9 x 5
LCM(9,10) = 90
Least Common Multiple of 9 and 10 by Prime Factorization
The solution above and all other related solutions were provided by the Least Common Multiple by Prime Factorization Application.
