Now, list down the factors of 417
:1,3,139,417
Now, list down the factors of 305
:1,5,61,305
Greatest Common Factor
We found the factors 417,305 . The biggest common factor number is the GCF number.
So the greatest common factor 417,305 is 1.
Lets's calculate LCM of 257,436
Given numbers has no common factors except 1. So, there LCM is their product i.e 112052
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/112052
Therefore, the GCF of Fractions 417/257,305/436 is 1/112052
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 257,436 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,436) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,436) x common factors =1 x 1 = 1
LCM(257,436) = ( 257 × 436 ) / 1
LCM(257,436) = 112052 / 1
LCM(257,436) = 112052
