Least Common Multiple of 21, 71, 646

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

• Least Common Multiple of 21, 71, 646 by common division method
• Least Common Multiple of 21, 71, 646 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 963186

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 21,71,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,71,646) = 1

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

GCF(21,71,646) x common factors =1 x 1 = 1

LCM(21,71,646) = ( 21 × 71 × 646 ) / 1

LCM(21,71,646) = 963186 / 1

LCM(21,71,646) = 963186

∴ Least Common Multiple of 21,71,646 is 963186

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

• LCM of 69, 32, 789
• LCM of 62, 24, 678
• LCM of 51, 28, 966
• LCM of 21, 83, 655
