Least Common Multiple of 51, 86, 43, 15

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

• Least Common Multiple of 51, 86, 43, 15 by common division method
• Least Common Multiple of 51, 86, 43, 15 with GCF Formula

∴ So the LCM of the given numbers is 3 x 43 x 17 x 2 x 1 x 5 = 21930

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 51,86,43,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(51,86,43,15) = 1

common factors(in case of two or more numbers have common factors) = 129

GCF(51,86,43,15) x common factors =1 x 129 = 129

LCM(51,86,43,15) = ( 51 × 86 × 43 × 15 ) / 129

LCM(51,86,43,15) = 2828970 / 129

LCM(51,86,43,15) = 21930

∴ Least Common Multiple of 51,86,43,15 is 21930
