So the greatest common factor 823,786 is 1.
Lets's calculate LCM of 837,172
Given numbers has no common factors except 1. So, there LCM is their product i.e 143964
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/143964
Therefore, the GCF of Fractions 823/837,786/172 is 1/143964
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 837,172 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(837,172) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(837,172) x common factors =1 x 1 = 1
LCM(837,172) = ( 837 × 172 ) / 1
LCM(837,172) = 143964 / 1
LCM(837,172) = 143964
