Greatest Common Factor
We found the factors 90,3141 . The biggest common factor number is the GCF number.
So the greatest common factor 90,3141 is 9.
Lets's calculate LCM of 251,6438
Given numbers has no common factors except 1. So, there LCM is their product i.e 1615938
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/1615938
Therefore, the GCF of Fractions 90/251,3141/6438 is 9/1615938
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 251,6438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(251,6438) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(251,6438) x common factors =1 x 1 = 1
LCM(251,6438) = ( 251 × 6438 ) / 1
LCM(251,6438) = 1615938 / 1
LCM(251,6438) = 1615938
