:1,7,313,2191
Now, list down the factors of 1699
:1,1699
Greatest Common Factor
We found the factors 2191,1699 . The biggest common factor number is the GCF number.
So the greatest common factor 2191,1699 is 1.
Lets's calculate LCM of 421,421
421 | 421, 421 |
1, 1 |
∴ So the LCM of the given numbers is 421 x 1 x 1 = 421
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/421
Therefore, the GCF of Fractions 2191/421,1699/421 is 1/421
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 421,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(421,421) = 421
common factors(in case of two or more numbers have common factors) = 1
GCF(421,421) x common factors =421 x 1 = 421
LCM(421,421) = ( 421 × 421 ) / 421
LCM(421,421) = 177241 / 421
LCM(421,421) = 421
