Now, list down the factors of 788
:1,2,4,197,394,788
Now, list down the factors of 305
:1,5,61,305
Greatest Common Factor
We found the factors 788,305 . The biggest common factor number is the GCF number.
So the greatest common factor 788,305 is 1.
Lets's calculate LCM of 311,987
Given numbers has no common factors except 1. So, there LCM is their product i.e 306957
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/306957
Therefore, the GCF of Fractions 788/311,305/987 is 1/306957
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 311,987 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(311,987) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(311,987) x common factors =1 x 1 = 1
LCM(311,987) = ( 311 × 987 ) / 1
LCM(311,987) = 306957 / 1
LCM(311,987) = 306957
