Least Common Multiple of 21, 87, 591

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

• Least Common Multiple of 21, 87, 591 by common division method
• Least Common Multiple of 21, 87, 591 with GCF Formula

∴ So the LCM of the given numbers is 3 x 7 x 29 x 197 = 119973

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 21,87,591 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,87,591) = 3

common factors(in case of two or more numbers have common factors) = 3

GCF(21,87,591) x common factors =3 x 3 = 9

LCM(21,87,591) = ( 21 × 87 × 591 ) / 9

LCM(21,87,591) = 1079757 / 9

LCM(21,87,591) = 119973

∴ Least Common Multiple of 21,87,591 is 119973
