Least Common Multiple of 643, 756

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

• Least Common Multiple of 643, 756 by common division method
• Least Common Multiple of 643, 756 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 486108

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 643,756 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,756) = 1

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

GCF(643,756) x common factors =1 x 1 = 1

LCM(643,756) = ( 643 × 756 ) / 1

LCM(643,756) = 486108 / 1

LCM(643,756) = 486108

∴ Least Common Multiple of 643,756 is 486108

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

• LCM of 177, 399
• LCM of 812, 921
• LCM of 146, 102
• LCM of 217, 382
• LCM of 155, 784
