Lets's calculate GCF of 303,255
| 3 | 303, 255 |
| 101, 85 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 303
:1,3,101,303
Now, list down the factors of 255
:1,3,5,15,17,51,85,255
Greatest Common Factor
We found the factors 303,255 . The biggest common factor number is the GCF number.
So the greatest common factor 303,255 is 3.
Lets's calculate LCM of 257,811
Given numbers has no common factors except 1. So, there LCM is their product i.e 208427
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/208427
Therefore, the GCF of Fractions 303/257,255/811 is 3/208427
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 257,811 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,811) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,811) x common factors =1 x 1 = 1
LCM(257,811) = ( 257 × 811 ) / 1
LCM(257,811) = 208427 / 1
LCM(257,811) = 208427
