Greatest Common Factor
We found the factors 97,90,77,900 . The biggest common factor number is the GCF number.
So the greatest common factor 97,90,77,900 is 1.
Lets's calculate LCM of 31,67,77,29
Given numbers has no common factors except 1. So, there LCM is their product i.e 4637941
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4637941
Therefore, the GCF of Fractions 97/31,90/67,77/77,900/29 is 1/4637941
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 31,67,77,29 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,67,77,29) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,67,77,29) x common factors =1 x 1 = 1
LCM(31,67,77,29) = ( 31 × 67 × 77 × 29 ) / 1
LCM(31,67,77,29) = 4637941 / 1
LCM(31,67,77,29) = 4637941
