Factors of 4279
List of positive integer factors of 4279 that divides 4279 without a remainder.
1,11,389,4279
Greatest Common Factor
We found the factors 131,4279 . The biggest common factor number is the GCF number.
So the greatest common factor 131,4279 is 1.
Lets's calculate LCM of 208,1790
2 | 208, 1790 |
104, 895 |
∴ So the LCM of the given numbers is 2 x 104 x 895 = 186160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/186160
Therefore, the GCF of Fractions 131/208,4279/1790 is 1/186160
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 208,1790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(208,1790) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(208,1790) x common factors =2 x 1 = 2
LCM(208,1790) = ( 208 × 1790 ) / 2
LCM(208,1790) = 372320 / 2
LCM(208,1790) = 186160
