Least Common Multiple of 15,88,55,642 with GCF Formula

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 15,88,55,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,88,55,642) = 1

common factors(in case of two or more numbers have common factors) = 330

GCF(15,88,55,642) x common factors =1 x 330 = 330

LCM(15,88,55,642) = ( 15 × 88 × 55 × 642 ) / 330

LCM(15,88,55,642) = 46609200 / 330

LCM(15,88,55,642) = 141240

∴ Least Common Multiple of 15,88,55,642 is 141240
