Least Common Multiple of 81, 20, 60, 115 with GCF Formula

Least Common Multiple of 81,20,60,115

Least Common Multiple (LCM) of 81,20,60,115 is 37260

2	81, 20, 60, 115
2	81, 10, 30, 115
3	81, 5, 15, 115
5	27, 5, 5, 115
	27, 1, 1, 23

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 27 x 1 x 1 x 23 = 37260

Least Common Multiple of 81,20,60,115 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 81,20,60,115 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,20,60,115) = 1

common factors(in case of two or more numbers have common factors) = 300

GCF(81,20,60,115) x common factors =1 x 300 = 300

LCM(81,20,60,115) = ( 81 × 20 × 60 × 115 ) / 300

LCM(81,20,60,115) = 11178000 / 300

LCM(81,20,60,115) = 37260

∴ Least Common Multiple of 81,20,60,115 is 37260
