Greatest Common Factor
We found the factors 720,844 . The biggest common factor number is the GCF number.
So the greatest common factor 720,844 is 4.
Lets's calculate LCM of 847,782
Given numbers has no common factors except 1. So, there LCM is their product i.e 662354
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/662354
Therefore, the GCF of Fractions 720/847,844/782 is 4/662354
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 847,782 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(847,782) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(847,782) x common factors =1 x 1 = 1
LCM(847,782) = ( 847 × 782 ) / 1
LCM(847,782) = 662354 / 1
LCM(847,782) = 662354
