Least Common Multiple of 690, 138, 618

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

• Least Common Multiple of 690, 138, 618 by common division method
• Least Common Multiple of 690, 138, 618 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 23 x 5 x 1 x 103 = 71070

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 690,138,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(690,138,618) = 6

common factors(in case of two or more numbers have common factors) = 138

GCF(690,138,618) x common factors =6 x 138 = 828

LCM(690,138,618) = ( 690 × 138 × 618 ) / 828

LCM(690,138,618) = 58845960 / 828

LCM(690,138,618) = 71070

∴ Least Common Multiple of 690,138,618 is 71070

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

• LCM of 475, 217, 891
• LCM of 625, 351, 712
