:1,2,5,10,97,194,485,970
Greatest Common Factor
We found the factors 36,761,970 . The biggest common factor number is the GCF number.
So the greatest common factor 36,761,970 is 1.
Lets's calculate LCM of 45,13,139
Given numbers has no common factors except 1. So, there LCM is their product i.e 81315
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/81315
Therefore, the GCF of Fractions 36/45,761/13,970/139 is 1/81315
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 45,13,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,13,139) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(45,13,139) x common factors =1 x 1 = 1
LCM(45,13,139) = ( 45 × 13 × 139 ) / 1
LCM(45,13,139) = 81315 / 1
LCM(45,13,139) = 81315
