Least Common Multiple of 391, 639

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

• Least Common Multiple of 391, 639 by common division method
• Least Common Multiple of 391, 639 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 249849

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 391,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(391,639) = 1

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

GCF(391,639) x common factors =1 x 1 = 1

LCM(391,639) = ( 391 × 639 ) / 1

LCM(391,639) = 249849 / 1

LCM(391,639) = 249849

∴ Least Common Multiple of 391,639 is 249849

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

• LCM of 649, 591
• LCM of 133, 371
• LCM of 245, 476
• LCM of 992, 375
