Least Common Multiple of 686, 404

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

• Least Common Multiple of 686, 404 by common division method
• Least Common Multiple of 686, 404 with GCF Formula

∴ So the LCM of the given numbers is 2 x 343 x 202 = 138572

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 686,404 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(686,404) = 2

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

GCF(686,404) x common factors =2 x 1 = 2

LCM(686,404) = ( 686 × 404 ) / 2

LCM(686,404) = 277144 / 2

LCM(686,404) = 138572

∴ Least Common Multiple of 686,404 is 138572

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

• LCM of 252, 293
• LCM of 718, 700
• LCM of 270, 915
• LCM of 724, 900
• LCM of 993, 507
