Greatest Common Factor
We found the factors 979,505 . The biggest common factor number is the GCF number.
So the greatest common factor 979,505 is 1.
Lets's calculate LCM of 517,538
Given numbers has no common factors except 1. So, there LCM is their product i.e 278146
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/278146
Therefore, the GCF of Fractions 979/517,505/538 is 1/278146
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 517,538 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(517,538) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(517,538) x common factors =1 x 1 = 1
LCM(517,538) = ( 517 × 538 ) / 1
LCM(517,538) = 278146 / 1
LCM(517,538) = 278146
