Greatest Common Factor
We found the factors 47,12,60,15 . The biggest common factor number is the GCF number.
So the greatest common factor 47,12,60,15 is 1.
Lets's calculate LCM of 61,17,71,35
Given numbers has no common factors except 1. So, there LCM is their product i.e 2576945
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2576945
Therefore, the GCF of Fractions 47/61,12/17,60/71,15/35 is 1/2576945
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 61,17,71,35 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,17,71,35) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,17,71,35) x common factors =1 x 1 = 1
LCM(61,17,71,35) = ( 61 × 17 × 71 × 35 ) / 1
LCM(61,17,71,35) = 2576945 / 1
LCM(61,17,71,35) = 2576945
