Least Common Multiple of 51, 51, 646

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

• Least Common Multiple of 51, 51, 646 by common division method
• Least Common Multiple of 51, 51, 646 with GCF Formula

∴ So the LCM of the given numbers is 3 x 17 x 1 x 1 x 38 = 1938

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 51,51,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,51,646) = 17

common factors(in case of two or more numbers have common factors) = 51

GCF(51,51,646) x common factors =17 x 51 = 867

LCM(51,51,646) = ( 51 × 51 × 646 ) / 867

LCM(51,51,646) = 1680246 / 867

LCM(51,51,646) = 1938

∴ Least Common Multiple of 51,51,646 is 1938

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

• LCM of 90, 17, 540
• LCM of 48, 43, 698
