Least common multiple (LCM) of 45, 64, 31, 620 is 89280.

LCM(45, 64, 31, 620) = 89280

LCM of 45, 64, 31, 620

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

Least Common Multiple of 45, 64, 31, 620 by common division method
Least Common Multiple of 45, 64, 31, 620 with GCF Formula

Least Common Multiple of 45,64,31,620

Least Common Multiple (LCM) of 45,64,31,620 is 89280

2	45, 64, 31, 620
2	45, 32, 31, 310
5	45, 16, 31, 155
31	9, 16, 31, 31
	9, 16, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 5 x 31 x 9 x 16 x 1 x 1 = 89280

Least Common Multiple of 45,64,31,620 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 45,64,31,620 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(45,64,31,620) = 1

common factors(in case of two or more numbers have common factors) = 620

GCF(45,64,31,620) x common factors =1 x 620 = 620

LCM(45,64,31,620) = ( 45 × 64 × 31 × 620 ) / 620

LCM(45,64,31,620) = 55353600 / 620

LCM(45,64,31,620) = 89280

∴ Least Common Multiple of 45,64,31,620 is 89280
