| 3 | 513, 5421 |
| 171, 1807 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 513
:1,3,9,19,27,57,171,513
Now, list down the factors of 5421
:1,3,13,39,139,417,1807,5421
Greatest Common Factor
We found the factors 513,5421 . The biggest common factor number is the GCF number.
So the greatest common factor 513,5421 is 3.
Lets's calculate LCM of 457,438
Given numbers has no common factors except 1. So, there LCM is their product i.e 200166
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/200166
Therefore, the GCF of Fractions 513/457,5421/438 is 3/200166
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 457,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(457,438) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(457,438) x common factors =1 x 1 = 1
LCM(457,438) = ( 457 × 438 ) / 1
LCM(457,438) = 200166 / 1
LCM(457,438) = 200166
