Least Common Multiple of 287, 861, 69

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

• Least Common Multiple of 287, 861, 69 by common division method
• Least Common Multiple of 287, 861, 69 with GCF Formula

∴ So the LCM of the given numbers is 3 x 7 x 41 x 1 x 1 x 23 = 19803

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 287,861,69 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(287,861,69) = 1

common factors(in case of two or more numbers have common factors) = 861

GCF(287,861,69) x common factors =1 x 861 = 861

LCM(287,861,69) = ( 287 × 861 × 69 ) / 861

LCM(287,861,69) = 17050383 / 861

LCM(287,861,69) = 19803

∴ Least Common Multiple of 287,861,69 is 19803

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

• LCM of 323, 561, 90
• LCM of 609, 471, 48
