Least Common Multiple of 643, 523

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

• Least Common Multiple of 643, 523 by common division method
• Least Common Multiple of 643, 523 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 336289

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 643,523 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,523) = 1

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

GCF(643,523) x common factors =1 x 1 = 1

LCM(643,523) = ( 643 × 523 ) / 1

LCM(643,523) = 336289 / 1

LCM(643,523) = 336289

∴ Least Common Multiple of 643,523 is 336289

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

• LCM of 280, 422
• LCM of 642, 355
• LCM of 931, 429
