Least Common Multiple of 421, 408

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

• Least Common Multiple of 421, 408 by common division method
• Least Common Multiple of 421, 408 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 171768

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 421,408 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(421,408) = 1

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

GCF(421,408) x common factors =1 x 1 = 1

LCM(421,408) = ( 421 × 408 ) / 1

LCM(421,408) = 171768 / 1

LCM(421,408) = 171768

∴ Least Common Multiple of 421,408 is 171768

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

• LCM of 665, 629
• LCM of 110, 549
• LCM of 244, 662
• LCM of 635, 929
• LCM of 362, 141
