We found the factors 815,7930 . The biggest common factor number is the GCF number.
So the greatest common factor 815,7930 is 5.
Lets's calculate LCM of 983,318
Given numbers has no common factors except 1. So, there LCM is their product i.e 312594
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/312594
Therefore, the GCF of Fractions 815/983,7930/318 is 5/312594
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 983,318 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(983,318) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(983,318) x common factors =1 x 1 = 1
LCM(983,318) = ( 983 × 318 ) / 1
LCM(983,318) = 312594 / 1
LCM(983,318) = 312594
Here are some samples of GCF of Fractions calculations.
