Least Common Multiple of 686, 6978

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

• Least Common Multiple of 686, 6978 by common division method
• Least Common Multiple of 686, 6978 with GCF Formula

∴ So the LCM of the given numbers is 2 x 343 x 3489 = 2393454

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 686,6978 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(686,6978) = 2

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

GCF(686,6978) x common factors =2 x 1 = 2

LCM(686,6978) = ( 686 × 6978 ) / 2

LCM(686,6978) = 4786908 / 2

LCM(686,6978) = 2393454

∴ Least Common Multiple of 686,6978 is 2393454

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

• LCM of 592, 6177
• LCM of 534, 8025
• LCM of 919, 6420
• LCM of 100, 3975
