Greatest Common Factor
We found the factors 477,691 . The biggest common factor number is the GCF number.
So the greatest common factor 477,691 is 1.
Lets's calculate LCM of 757,540
Given numbers has no common factors except 1. So, there LCM is their product i.e 408780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/408780
Therefore, the GCF of Fractions 477/757,691/540 is 1/408780
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 757,540 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(757,540) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(757,540) x common factors =1 x 1 = 1
LCM(757,540) = ( 757 × 540 ) / 1
LCM(757,540) = 408780 / 1
LCM(757,540) = 408780
