Greatest Common Factor
We found the factors 100,520 . The biggest common factor number is the GCF number.
So the greatest common factor 100,520 is 20.
Lets's calculate LCM of 858,919
Given numbers has no common factors except 1. So, there LCM is their product i.e 788502
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/788502
Therefore, the GCF of Fractions 100/858,520/919 is 20/788502
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 858,919 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(858,919) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(858,919) x common factors =1 x 1 = 1
LCM(858,919) = ( 858 × 919 ) / 1
LCM(858,919) = 788502 / 1
LCM(858,919) = 788502
