Least Common Multiple of 686, 688, 87

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

• Least Common Multiple of 686, 688, 87 by common division method
• Least Common Multiple of 686, 688, 87 with GCF Formula

∴ So the LCM of the given numbers is 2 x 343 x 344 x 87 = 20530608

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 686,688,87 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(686,688,87) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(686,688,87) x common factors =1 x 2 = 2

LCM(686,688,87) = ( 686 × 688 × 87 ) / 2

LCM(686,688,87) = 41061216 / 2

LCM(686,688,87) = 20530608

∴ Least Common Multiple of 686,688,87 is 20530608

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

• LCM of 214, 600, 19
• LCM of 328, 143, 62
• LCM of 479, 750, 61
