:1,2,11,13,22,26,143,286
Greatest Common Factor
We found the factors 985,286 . The biggest common factor number is the GCF number.
So the greatest common factor 985,286 is 1.
Lets's calculate LCM of 685,251
Given numbers has no common factors except 1. So, there LCM is their product i.e 171935
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/171935
Therefore, the GCF of Fractions 985/685,286/251 is 1/171935
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 685,251 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,251) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(685,251) x common factors =1 x 1 = 1
LCM(685,251) = ( 685 × 251 ) / 1
LCM(685,251) = 171935 / 1
LCM(685,251) = 171935
