Least Common Multiple of 56, 45, 69, 81, 345 with GCF Formula

Least Common Multiple of 56,45,69,81,345

Least Common Multiple (LCM) of 56,45,69,81,345 is 521640

3	56, 45, 69, 81, 345
3	56, 15, 23, 27, 115
5	56, 5, 23, 9, 115
23	56, 1, 23, 9, 23
	56, 1, 1, 9, 1

∴ So the LCM of the given numbers is 3 x 3 x 5 x 23 x 56 x 1 x 1 x 9 x 1 = 521640

Least Common Multiple of 56,45,69,81,345 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 56,45,69,81,345 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(56,45,69,81,345) = 1

common factors(in case of two or more numbers have common factors) = 9315

GCF(56,45,69,81,345) x common factors =1 x 9315 = 9315

LCM(56,45,69,81,345) = ( 56 × 45 × 69 × 81 × 345 ) / 9315

LCM(56,45,69,81,345) = 4859076600 / 9315

LCM(56,45,69,81,345) = 521640

∴ Least Common Multiple of 56,45,69,81,345 is 521640
