Least Common Multiple of 643, 85

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

• Least Common Multiple of 643, 85 by common division method
• Least Common Multiple of 643, 85 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 54655

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 643,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,85) = 1

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

GCF(643,85) x common factors =1 x 1 = 1

LCM(643,85) = ( 643 × 85 ) / 1

LCM(643,85) = 54655 / 1

LCM(643,85) = 54655

∴ Least Common Multiple of 643,85 is 54655

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

• LCM of 642, 35
• LCM of 583, 34
• LCM of 242, 19
• LCM of 413, 55
• LCM of 116, 43
