Greatest Common Factor
We found the factors 2015,8742 . The biggest common factor number is the GCF number.
So the greatest common factor 2015,8742 is 31.
Lets's calculate LCM of 505,987
Given numbers has no common factors except 1. So, there LCM is their product i.e 498435
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 31/498435
Therefore, the GCF of Fractions 2015/505,8742/987 is 31/498435
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 505,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(505,987) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(505,987) x common factors =1 x 1 = 1
LCM(505,987) = ( 505 × 987 ) / 1
LCM(505,987) = 498435 / 1
LCM(505,987) = 498435
