Least Common Multiple of 643, 280

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

• Least Common Multiple of 643, 280 by common division method
• Least Common Multiple of 643, 280 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 180040

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 643,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,280) = 1

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

GCF(643,280) x common factors =1 x 1 = 1

LCM(643,280) = ( 643 × 280 ) / 1

LCM(643,280) = 180040 / 1

LCM(643,280) = 180040

∴ Least Common Multiple of 643,280 is 180040

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

• LCM of 846, 808
• LCM of 855, 126
• LCM of 623, 439
• LCM of 343, 699
• LCM of 221, 571
