Least Common Multiple of 18, 21, 63, 745

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

• Least Common Multiple of 18, 21, 63, 745 by common division method
• Least Common Multiple of 18, 21, 63, 745 with GCF Formula

∴ So the LCM of the given numbers is 3 x 3 x 7 x 2 x 1 x 1 x 745 = 93870

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 18,21,63,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(18,21,63,745) = 1

common factors(in case of two or more numbers have common factors) = 189

GCF(18,21,63,745) x common factors =1 x 189 = 189

LCM(18,21,63,745) = ( 18 × 21 × 63 × 745 ) / 189

LCM(18,21,63,745) = 17741430 / 189

LCM(18,21,63,745) = 93870

∴ Least Common Multiple of 18,21,63,745 is 93870
