Greatest Common Factor
We found the factors 277,145 . The biggest common factor number is the GCF number.
So the greatest common factor 277,145 is 1.
Lets's calculate LCM of 657,470
Given numbers has no common factors except 1. So, there LCM is their product i.e 308790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/308790
Therefore, the GCF of Fractions 277/657,145/470 is 1/308790
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 657,470 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(657,470) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(657,470) x common factors =1 x 1 = 1
LCM(657,470) = ( 657 × 470 ) / 1
LCM(657,470) = 308790 / 1
LCM(657,470) = 308790
