:1,3,7,9,13,21,39,63,91,117,273,819
Greatest Common Factor
We found the factors 882,819 . The biggest common factor number is the GCF number.
So the greatest common factor 882,819 is 63.
Lets's calculate LCM of 899,705
Given numbers has no common factors except 1. So, there LCM is their product i.e 633795
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 63/633795
Therefore, the GCF of Fractions 882/899,819/705 is 63/633795
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 899,705 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(899,705) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(899,705) x common factors =1 x 1 = 1
LCM(899,705) = ( 899 × 705 ) / 1
LCM(899,705) = 633795 / 1
LCM(899,705) = 633795
