Greatest Common Factor
We found the factors 91,923,481 . The biggest common factor number is the GCF number.
So the greatest common factor 91,923,481 is 13.
Lets's calculate LCM of 392,611,621
Given numbers has no common factors except 1. So, there LCM is their product i.e 148736952
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/148736952
Therefore, the GCF of Fractions 91/392,923/611,481/621 is 13/148736952
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 392,611,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(392,611,621) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(392,611,621) x common factors =1 x 1 = 1
LCM(392,611,621) = ( 392 × 611 × 621 ) / 1
LCM(392,611,621) = 148736952 / 1
LCM(392,611,621) = 148736952
