Lets's calculate LCM of 859,307
Given numbers has no common factors except 1. So, there LCM is their product i.e 263713
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/263713
Therefore, the GCF of Fractions 813/859,920/307 is 1/263713
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 859,307 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(859,307) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(859,307) x common factors =1 x 1 = 1
LCM(859,307) = ( 859 × 307 ) / 1
LCM(859,307) = 263713 / 1
LCM(859,307) = 263713
