1,3,19,57,71,213,1349,4047
Greatest Common Factor
We found the factors 828,4047 . The biggest common factor number is the GCF number.
So the greatest common factor 828,4047 is 3.
Lets's calculate LCM of 97,928
Given numbers has no common factors except 1. So, there LCM is their product i.e 90016
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/90016
Therefore, the GCF of Fractions 828/97,4047/928 is 3/90016
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 97,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,928) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,928) x common factors =1 x 1 = 1
LCM(97,928) = ( 97 × 928 ) / 1
LCM(97,928) = 90016 / 1
LCM(97,928) = 90016
