:1,11,121
Now, list down the factors of 778
:1,2,389,778
Greatest Common Factor
We found the factors 121,778 . The biggest common factor number is the GCF number.
So the greatest common factor 121,778 is 1.
Lets's calculate LCM of 17,3994
Given numbers has no common factors except 1. So, there LCM is their product i.e 67898
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/67898
Therefore, the GCF of Fractions 121/17,778/3994 is 1/67898
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 17,3994 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,3994) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,3994) x common factors =1 x 1 = 1
LCM(17,3994) = ( 17 × 3994 ) / 1
LCM(17,3994) = 67898 / 1
LCM(17,3994) = 67898
