Greatest Common Factor
We found the factors 312,356 . The biggest common factor number is the GCF number.
So the greatest common factor 312,356 is 4.
Lets's calculate LCM of 857,134
Given numbers has no common factors except 1. So, there LCM is their product i.e 114838
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/114838
Therefore, the GCF of Fractions 312/857,356/134 is 4/114838
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 857,134 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(857,134) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(857,134) x common factors =1 x 1 = 1
LCM(857,134) = ( 857 × 134 ) / 1
LCM(857,134) = 114838 / 1
LCM(857,134) = 114838
