What is the Least Common Multiple of 33 and 44?
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.
Least common multiple (LCM) of 33 and 44 is 132.
LCM(33,44) = 132
Least Common Multiple of 33 and 44 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 33 and 44, than apply into the LCM equation.
GCF(33,44) = 11
LCM(33,44) = ( 33 × 44) / 11
LCM(33,44) = 1452 / 11
LCM(33,44) = 132
Least Common Multiple (LCM) of 33 and 44 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 33 and 44. First we will calculate the prime factors of 33 and 44.
Prime Factorization of 33
Prime factors of 33 are 3, 11. Prime factorization of 33 in exponential form is:
33 = 31 × 111
Prime Factorization of 44
Prime factors of 44 are 2, 11. Prime factorization of 44 in exponential form is:
44 = 22 × 111
Now multiplying the highest exponent prime factors to calculate the LCM of 33 and 44.
LCM(33,44) = 31 × 111 × 22
LCM(33,44) = 132
