Least Common Multiple of 661, 637

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

• Least Common Multiple of 661, 637 by common division method
• Least Common Multiple of 661, 637 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 421057

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 661,637 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(661,637) = 1

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

GCF(661,637) x common factors =1 x 1 = 1

LCM(661,637) = ( 661 × 637 ) / 1

LCM(661,637) = 421057 / 1

LCM(661,637) = 421057

∴ Least Common Multiple of 661,637 is 421057

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

• LCM of 403, 125
• LCM of 645, 430
• LCM of 934, 670
• LCM of 579, 158
• LCM of 337, 240
