Lets's calculate GCF of 11,78
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 11
:1,11
Now, list down the factors of 78
:1,2,3,6,13,26,39,78
Greatest Common Factor
We found the factors 11,78 . The biggest common factor number is the GCF number.
So the greatest common factor 11,78 is 1.
Lets's calculate LCM of 397,7959
Given numbers has no common factors except 1. So, there LCM is their product i.e 3159723
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3159723
Therefore, the GCF of Fractions 11/397,78/7959 is 1/3159723
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 397,7959 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(397,7959) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(397,7959) x common factors =1 x 1 = 1
LCM(397,7959) = ( 397 × 7959 ) / 1
LCM(397,7959) = 3159723 / 1
LCM(397,7959) = 3159723
