:1,3,7,17,21,51,119,357
Greatest Common Factor
We found the factors 658,357 . The biggest common factor number is the GCF number.
So the greatest common factor 658,357 is 7.
Lets's calculate LCM of 721,544
Given numbers has no common factors except 1. So, there LCM is their product i.e 392224
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/392224
Therefore, the GCF of Fractions 658/721,357/544 is 7/392224
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 721,544 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(721,544) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(721,544) x common factors =1 x 1 = 1
LCM(721,544) = ( 721 × 544 ) / 1
LCM(721,544) = 392224 / 1
LCM(721,544) = 392224
