What is the Least Common Multiple of 2041 and 2045?

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 of 2041 and 2045 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2041 and 2045, than apply into the LCM equation.

GCF(2041,2045) = 1
LCM(2041,2045) = ( 2041 × 2045) / 1
LCM(2041,2045) = 4173845 / 1
LCM(2041,2045) = 4173845

Least Common Multiple (LCM) of 2041 and 2045 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 2041 and 2045. First we will calculate the prime factors of 2041 and 2045.

Prime Factorization of 2041

Prime Factorization of 2045

Now multiplying the highest exponent prime factors to calculate the LCM of 2041 and 2045.

LCM(2041,2045) = 13¹ × 157¹ × 5¹ × 409¹
LCM(2041,2045) = 4173845
