:1,379
Now, list down the factors of 991
:1,991
Greatest Common Factor
We found the factors 379,991 . The biggest common factor number is the GCF number.
So the greatest common factor 379,991 is 1.
Lets's calculate LCM of 68,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 17476
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17476
Therefore, the GCF of Fractions 379/68,991/257 is 1/17476
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 68,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(68,257) x common factors =1 x 1 = 1
LCM(68,257) = ( 68 × 257 ) / 1
LCM(68,257) = 17476 / 1
LCM(68,257) = 17476
