Least Common Multiple of 643, 628

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

• Least Common Multiple of 643, 628 by common division method
• Least Common Multiple of 643, 628 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 403804

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 643,628 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,628) = 1

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

GCF(643,628) x common factors =1 x 1 = 1

LCM(643,628) = ( 643 × 628 ) / 1

LCM(643,628) = 403804 / 1

LCM(643,628) = 403804

∴ Least Common Multiple of 643,628 is 403804

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

• LCM of 780, 309
• LCM of 694, 253
• LCM of 283, 154
• LCM of 675, 196
• LCM of 585, 427
