:1,821
Greatest Common Factor
We found the factors 816,821 . The biggest common factor number is the GCF number.
So the greatest common factor 816,821 is 1.
Lets's calculate LCM of 995,774
Given numbers has no common factors except 1. So, there LCM is their product i.e 770130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/770130
Therefore, the GCF of Fractions 816/995,821/774 is 1/770130
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 995,774 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(995,774) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(995,774) x common factors =1 x 1 = 1
LCM(995,774) = ( 995 × 774 ) / 1
LCM(995,774) = 770130 / 1
LCM(995,774) = 770130
