Greatest Common Factor

We found the factors 39,45,383 . The biggest common factor number is the GCF number.
So the greatest common factor 39,45,383 is 1.

Lets's calculate LCM of 80,25,18

2 80, 25, 18
5 40, 25, 9
8, 5, 9

∴ So the LCM of the given numbers is 2 x 5 x 8 x 5 x 9 = 3600

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3600

Therefore, the GCF of Fractions 39/80,45/25,383/18 is 1/3600

Least Common Multiple of 80,25,18 with GCF Formula

Least Common Multiple of 80,25,18 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 80,25,18 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,25,18) = 1

common factors(in case of two or more numbers have common factors) = 10

GCF(80,25,18) x common factors =1 x 10 = 10

LCM(80,25,18) = ( 80 × 25 × 18 ) / 10

LCM(80,25,18) = 36000 / 10

LCM(80,25,18) = 3600
