Now, list down the factors of 91
:1,7,13,91
Now, list down the factors of 80
:1,2,4,5,8,10,16,20,40,80
Greatest Common Factor
We found the factors 91,80 . The biggest common factor number is the GCF number.
So the greatest common factor 91,80 is 1.
Lets's calculate LCM of 909,8956
Given numbers has no common factors except 1. So, there LCM is their product i.e 8141004
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8141004
Therefore, the GCF of Fractions 91/909,80/8956 is 1/8141004
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 909,8956 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(909,8956) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(909,8956) x common factors =1 x 1 = 1
LCM(909,8956) = ( 909 × 8956 ) / 1
LCM(909,8956) = 8141004 / 1
LCM(909,8956) = 8141004
