Greatest Common Factor
We found the factors 77,329,255 . The biggest common factor number is the GCF number.
So the greatest common factor 77,329,255 is 1.
Lets's calculate LCM of 40,49,307
Given numbers has no common factors except 1. So, there LCM is their product i.e 601720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/601720
Therefore, the GCF of Fractions 77/40,329/49,255/307 is 1/601720
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 40,49,307 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,49,307) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(40,49,307) x common factors =1 x 1 = 1
LCM(40,49,307) = ( 40 × 49 × 307 ) / 1
LCM(40,49,307) = 601720 / 1
LCM(40,49,307) = 601720
