Least Common Multiple of 643, 693

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

• Least Common Multiple of 643, 693 by common division method
• Least Common Multiple of 643, 693 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 445599

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 643,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(643,693) = 1

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

GCF(643,693) x common factors =1 x 1 = 1

LCM(643,693) = ( 643 × 693 ) / 1

LCM(643,693) = 445599 / 1

LCM(643,693) = 445599

∴ Least Common Multiple of 643,693 is 445599

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

• LCM of 271, 555
• LCM of 681, 906
• LCM of 883, 227
• LCM of 216, 480
• LCM of 375, 761
