1,2,5,10,11,22,25,50,55,110,275,550
Greatest Common Factor
We found the factors 68,983,550 . The biggest common factor number is the GCF number.
So the greatest common factor 68,983,550 is 1.
Lets's calculate LCM of 31,88,79
Given numbers has no common factors except 1. So, there LCM is their product i.e 215512
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/215512
Therefore, the GCF of Fractions 68/31,983/88,550/79 is 1/215512
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 31,88,79 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,88,79) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,88,79) x common factors =1 x 1 = 1
LCM(31,88,79) = ( 31 × 88 × 79 ) / 1
LCM(31,88,79) = 215512 / 1
LCM(31,88,79) = 215512
