Greatest Common Factor
We found the factors 780,3933 . The biggest common factor number is the GCF number.
So the greatest common factor 780,3933 is 3.
Lets's calculate LCM of 77,599
Given numbers has no common factors except 1. So, there LCM is their product i.e 46123
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/46123
Therefore, the GCF of Fractions 780/77,3933/599 is 3/46123
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 77,599 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,599) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,599) x common factors =1 x 1 = 1
LCM(77,599) = ( 77 × 599 ) / 1
LCM(77,599) = 46123 / 1
LCM(77,599) = 46123
Here are some samples of GCF of Fractions calculations.
