Greatest Common Factor
We found the factors 7840,8708 . The biggest common factor number is the GCF number.
So the greatest common factor 7840,8708 is 28.
Lets's calculate LCM of 392,101
Given numbers has no common factors except 1. So, there LCM is their product i.e 39592
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/39592
Therefore, the GCF of Fractions 7840/392,8708/101 is 28/39592
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 392,101 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(392,101) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(392,101) x common factors =1 x 1 = 1
LCM(392,101) = ( 392 × 101 ) / 1
LCM(392,101) = 39592 / 1
LCM(392,101) = 39592
