Factors of 2671
List of positive integer factors of 2671 that divides 2671 without a remainder.
1,2671
Greatest Common Factor
We found the factors 690,2671 . The biggest common factor number is the GCF number.
So the greatest common factor 690,2671 is 1.
Lets's calculate LCM of 788,892
2 | 788, 892 |
2 | 394, 446 |
197, 223 |
∴ So the LCM of the given numbers is 2 x 2 x 197 x 223 = 175724
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/175724
Therefore, the GCF of Fractions 690/788,2671/892 is 1/175724
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 788,892 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(788,892) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(788,892) x common factors =4 x 1 = 4
LCM(788,892) = ( 788 × 892 ) / 4
LCM(788,892) = 702896 / 4
LCM(788,892) = 175724
