We found the factors 70,255,223 . The biggest common factor number is the GCF number.
So the greatest common factor 70,255,223 is 1.

Lets's calculate LCM of 90,56,800

2 90, 56, 800
2 45, 28, 400
2 45, 14, 200
5 45, 7, 100
9, 7, 20

∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 9 x 7 x 20 = 50400

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/50400

Therefore, the GCF of Fractions 70/90,255/56,223/800 is 1/50400

Least Common Multiple of 90,56,800 with GCF Formula

Least Common Multiple of 90,56,800 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 90,56,800 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,56,800) = 2

common factors(in case of two or more numbers have common factors) = 40

GCF(90,56,800) x common factors =2 x 40 = 80

LCM(90,56,800) = ( 90 × 56 × 800 ) / 80

LCM(90,56,800) = 4032000 / 80

LCM(90,56,800) = 50400
