Least Common Multiple of 420, 549, 90

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

• Least Common Multiple of 420, 549, 90 by common division method
• Least Common Multiple of 420, 549, 90 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 14 x 61 x 1 = 76860

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 420,549,90 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(420,549,90) = 3

common factors(in case of two or more numbers have common factors) = 90

GCF(420,549,90) x common factors =3 x 90 = 270

LCM(420,549,90) = ( 420 × 549 × 90 ) / 270

LCM(420,549,90) = 20752200 / 270

LCM(420,549,90) = 76860

∴ Least Common Multiple of 420,549,90 is 76860

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

• LCM of 952, 114, 84
• LCM of 130, 777, 74
