Least Common Multiple of 423, 1643

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

• Least Common Multiple of 423, 1643 by common division method
• Least Common Multiple of 423, 1643 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 694989

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 423,1643 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(423,1643) = 1

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

GCF(423,1643) x common factors =1 x 1 = 1

LCM(423,1643) = ( 423 × 1643 ) / 1

LCM(423,1643) = 694989 / 1

LCM(423,1643) = 694989

∴ Least Common Multiple of 423,1643 is 694989

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

• LCM of 318, 4410
• LCM of 309, 7322
• LCM of 995, 8323
• LCM of 572, 2114
• LCM of 256, 6792
