Now, list down the factors of 788
:1,2,4,197,394,788
Now, list down the factors of 101
:1,101
Greatest Common Factor
We found the factors 788,101 . The biggest common factor number is the GCF number.
So the greatest common factor 788,101 is 1.
Lets's calculate LCM of 661,617
Given numbers has no common factors except 1. So, there LCM is their product i.e 407837
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/407837
Therefore, the GCF of Fractions 788/661,101/617 is 1/407837
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 661,617 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(661,617) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(661,617) x common factors =1 x 1 = 1
LCM(661,617) = ( 661 × 617 ) / 1
LCM(661,617) = 407837 / 1
LCM(661,617) = 407837
