Greatest Common Factor
We found the factors 369,173,220 . The biggest common factor number is the GCF number.
So the greatest common factor 369,173,220 is 1.
Lets's calculate LCM of 29,31,61
Given numbers has no common factors except 1. So, there LCM is their product i.e 54839
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54839
Therefore, the GCF of Fractions 369/29,173/31,220/61 is 1/54839
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 29,31,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,31,61) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(29,31,61) x common factors =1 x 1 = 1
LCM(29,31,61) = ( 29 × 31 × 61 ) / 1
LCM(29,31,61) = 54839 / 1
LCM(29,31,61) = 54839
