Least Common Multiple of 687, 6420

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

• Least Common Multiple of 687, 6420 by common division method
• Least Common Multiple of 687, 6420 with GCF Formula

∴ So the LCM of the given numbers is 3 x 229 x 2140 = 1470180

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 687,6420 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(687,6420) = 3

common factors(in case of two or more numbers have common factors) = 1

GCF(687,6420) x common factors =3 x 1 = 3

LCM(687,6420) = ( 687 × 6420 ) / 3

LCM(687,6420) = 4410540 / 3

LCM(687,6420) = 1470180

∴ Least Common Multiple of 687,6420 is 1470180

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

• LCM of 595, 6391
• LCM of 928, 7946
• LCM of 870, 3095
• LCM of 422, 5519
