Least Common Multiple of 43, 421

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

• Least Common Multiple of 43, 421 by common division method
• Least Common Multiple of 43, 421 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 18103

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 43,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(43,421) = 1

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

GCF(43,421) x common factors =1 x 1 = 1

LCM(43,421) = ( 43 × 421 ) / 1

LCM(43,421) = 18103 / 1

LCM(43,421) = 18103

∴ Least Common Multiple of 43,421 is 18103

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

• LCM of 64, 274
• LCM of 55, 369
• LCM of 52, 534
• LCM of 10, 542
• LCM of 18, 511
