So the greatest common factor 721,776 is 1.
Lets's calculate LCM of 956,861
Given numbers has no common factors except 1. So, there LCM is their product i.e 823116
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/823116
Therefore, the GCF of Fractions 721/956,776/861 is 1/823116
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 956,861 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(956,861) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(956,861) x common factors =1 x 1 = 1
LCM(956,861) = ( 956 × 861 ) / 1
LCM(956,861) = 823116 / 1
LCM(956,861) = 823116
