:1,823
Greatest Common Factor
We found the factors 580,823 . The biggest common factor number is the GCF number.
So the greatest common factor 580,823 is 1.
Lets's calculate LCM of 782,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 774962
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/774962
Therefore, the GCF of Fractions 580/782,823/991 is 1/774962
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 782,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(782,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(782,991) x common factors =1 x 1 = 1
LCM(782,991) = ( 782 × 991 ) / 1
LCM(782,991) = 774962 / 1
LCM(782,991) = 774962
