Greatest Common Factor
We found the factors 504,489 . The biggest common factor number is the GCF number.
So the greatest common factor 504,489 is 3.
Lets's calculate LCM of 177,785
Given numbers has no common factors except 1. So, there LCM is their product i.e 138945
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/138945
Therefore, the GCF of Fractions 504/177,489/785 is 3/138945
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 177,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(177,785) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(177,785) x common factors =1 x 1 = 1
LCM(177,785) = ( 177 × 785 ) / 1
LCM(177,785) = 138945 / 1
LCM(177,785) = 138945
