Least Common Multiple of 89, 63, 98, 21

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

• Least Common Multiple of 89, 63, 98, 21 by common division method
• Least Common Multiple of 89, 63, 98, 21 with GCF Formula

∴ So the LCM of the given numbers is 3 x 7 x 89 x 3 x 14 x 1 = 78498

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 89,63,98,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(89,63,98,21) = 1

common factors(in case of two or more numbers have common factors) = 147

GCF(89,63,98,21) x common factors =1 x 147 = 147

LCM(89,63,98,21) = ( 89 × 63 × 98 × 21 ) / 147

LCM(89,63,98,21) = 11539206 / 147

LCM(89,63,98,21) = 78498

∴ Least Common Multiple of 89,63,98,21 is 78498
