Least Common Multiple of 21, 1931

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

• Least Common Multiple of 21, 1931 by common division method
• Least Common Multiple of 21, 1931 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 40551

The formula of LCM is LCM(a₁,a₂,a₃....,a_n) = ( a₁ × a₂ × a₃ × .... × a_n) / GCF(a₁,a₂,a₃....,a_n) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 21,1931 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,1931) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(21,1931) x common factors =1 x 1 = 1

LCM(21,1931) = ( 21 × 1931 ) / 1

LCM(21,1931) = 40551 / 1

LCM(21,1931) = 40551

∴ Least Common Multiple of 21,1931 is 40551

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 89, 5204
• LCM of 96, 6380
• LCM of 60, 8905
• LCM of 74, 2145
• LCM of 17, 3638
