Greatest Common Factor
We found the factors 840,4695 . The biggest common factor number is the GCF number.
So the greatest common factor 840,4695 is 15.
Lets's calculate LCM of 457,669
Given numbers has no common factors except 1. So, there LCM is their product i.e 305733
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/305733
Therefore, the GCF of Fractions 840/457,4695/669 is 15/305733
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 457,669 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(457,669) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(457,669) x common factors =1 x 1 = 1
LCM(457,669) = ( 457 × 669 ) / 1
LCM(457,669) = 305733 / 1
LCM(457,669) = 305733
