We found the factors 781,1470 . The biggest common factor number is the GCF number.
So the greatest common factor 781,1470 is 1.
Lets's calculate LCM of 799,218
Given numbers has no common factors except 1. So, there LCM is their product i.e 174182
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/174182
Therefore, the GCF of Fractions 781/799,1470/218 is 1/174182
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 799,218 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(799,218) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(799,218) x common factors =1 x 1 = 1
LCM(799,218) = ( 799 × 218 ) / 1
LCM(799,218) = 174182 / 1
LCM(799,218) = 174182
