Greatest Common Factor
We found the factors 63,70,64,81 . The biggest common factor number is the GCF number.
So the greatest common factor 63,70,64,81 is 1.
Lets's calculate LCM of 91,89,57,34
Given numbers has no common factors except 1. So, there LCM is their product i.e 15695862
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15695862
Therefore, the GCF of Fractions 63/91,70/89,64/57,81/34 is 1/15695862
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 91,89,57,34 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,89,57,34) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,89,57,34) x common factors =1 x 1 = 1
LCM(91,89,57,34) = ( 91 × 89 × 57 × 34 ) / 1
LCM(91,89,57,34) = 15695862 / 1
LCM(91,89,57,34) = 15695862
