Greatest Common Factor
We found the factors 77,84,630 . The biggest common factor number is the GCF number.
So the greatest common factor 77,84,630 is 7.
Lets's calculate LCM of 16,67,775
Given numbers has no common factors except 1. So, there LCM is their product i.e 830800
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/830800
Therefore, the GCF of Fractions 77/16,84/67,630/775 is 7/830800
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 16,67,775 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,67,775) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(16,67,775) x common factors =1 x 1 = 1
LCM(16,67,775) = ( 16 × 67 × 775 ) / 1
LCM(16,67,775) = 830800 / 1
LCM(16,67,775) = 830800
Here are some samples of GCF of Fractions calculations.
