Least Common Multiple of 72, 85, 34, 56, 63

Q: How to Find the LCM of 72, 85, 34, 56, 63 ?

Least Common Multiple of 72, 85, 34, 56, 63 = 42840 Step 1: Divide all the numbers with common prime numbers having remainder zero. Step 2: Then multiply all the prime factors with last row quotient of common division that is LCM(72, 85, 34, 56, 63) = 2 x 2 x 2 x 3 x 3 x 5 x 7 x 17 = 42840.

Least Common Multiple of 72,85,34,56,63

Least Common Multiple (LCM) of 72,85,34,56,63 is 42840

2	72, 85, 34, 56, 63
2	36, 85, 17, 28, 63
2	18, 85, 17, 14, 63
3	9, 85, 17, 7, 63
3	3, 85, 17, 7, 21
7	1, 85, 17, 7, 7
17	1, 85, 17, 1, 1
	1, 5, 1, 1, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 7 x 17 x 1 x 5 x 1 x 1 x 1 = 42840

Least Common Multiple of 72,85,34,56,63 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 72,85,34,56,63 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,85,34,56,63) = 1

common factors(in case of two or more numbers have common factors) = 17136

GCF(72,85,34,56,63) x common factors =1 x 17136 = 17136

LCM(72,85,34,56,63) = ( 72 × 85 × 34 × 56 × 63 ) / 17136

LCM(72,85,34,56,63) = 734106240 / 17136

LCM(72,85,34,56,63) = 42840

∴ Least Common Multiple of 72,85,34,56,63 is 42840
