Greatest Common Factor
We found the factors 126,756 . The biggest common factor number is the GCF number.
So the greatest common factor 126,756 is 126.
Lets's calculate LCM of 86,897
Given numbers has no common factors except 1. So, there LCM is their product i.e 77142
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 126/77142
Therefore, the GCF of Fractions 126/86,756/897 is 126/77142
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 86,897 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,897) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(86,897) x common factors =1 x 1 = 1
LCM(86,897) = ( 86 × 897 ) / 1
LCM(86,897) = 77142 / 1
LCM(86,897) = 77142
