So the greatest common factor 811,120 is 1.

Lets's calculate LCM of 755,680

5 755, 680
151, 136

∴ So the LCM of the given numbers is 5 x 151 x 136 = 102680

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/102680

Therefore, the GCF of Fractions 811/755,120/680 is 1/102680

Least Common Multiple of 755,680 with GCF Formula

Least Common Multiple of 755,680 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 755,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(755,680) = 5

common factors(in case of two or more numbers have common factors) = 1

GCF(755,680) x common factors =5 x 1 = 5

LCM(755,680) = ( 755 × 680 ) / 5

LCM(755,680) = 513400 / 5

LCM(755,680) = 102680
