Least Common Multiple of 3989, 5421

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

• Least Common Multiple of 3989, 5421 by common division method
• Least Common Multiple of 3989, 5421 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 21624369

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 3989,5421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(3989,5421) = 1

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

GCF(3989,5421) x common factors =1 x 1 = 1

LCM(3989,5421) = ( 3989 × 5421 ) / 1

LCM(3989,5421) = 21624369 / 1

LCM(3989,5421) = 21624369

∴ Least Common Multiple of 3989,5421 is 21624369

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

• LCM of 1134, 6465
• LCM of 5252, 6452
• LCM of 4422, 5874
• LCM of 8804, 8580
