Least Common Multiple of 690, 840, 60

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

• Least Common Multiple of 690, 840, 60 by common division method
• Least Common Multiple of 690, 840, 60 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 23 x 14 x 1 = 19320

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 690,840,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(690,840,60) = 30

common factors(in case of two or more numbers have common factors) = 60

GCF(690,840,60) x common factors =30 x 60 = 1800

LCM(690,840,60) = ( 690 × 840 × 60 ) / 1800

LCM(690,840,60) = 34776000 / 1800

LCM(690,840,60) = 19320

∴ Least Common Multiple of 690,840,60 is 19320

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