Greatest Common Factor
We found the factors 625,457 . The biggest common factor number is the GCF number.
So the greatest common factor 625,457 is 1.
Lets's calculate LCM of 457,309
Given numbers has no common factors except 1. So, there LCM is their product i.e 141213
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/141213
Therefore, the GCF of Fractions 625/457,457/309 is 1/141213
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 457,309 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(457,309) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(457,309) x common factors =1 x 1 = 1
LCM(457,309) = ( 457 × 309 ) / 1
LCM(457,309) = 141213 / 1
LCM(457,309) = 141213
