Factors of 2857
List of positive integer factors of 2857 that divides 2857 without a remainder.
1,2857
Greatest Common Factor
We found the factors 765,2857 . The biggest common factor number is the GCF number.
So the greatest common factor 765,2857 is 1.
Lets's calculate LCM of 685,140
5 | 685, 140 |
137, 28 |
∴ So the LCM of the given numbers is 5 x 137 x 28 = 19180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19180
Therefore, the GCF of Fractions 765/685,2857/140 is 1/19180
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 685,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,140) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(685,140) x common factors =5 x 1 = 5
LCM(685,140) = ( 685 × 140 ) / 5
LCM(685,140) = 95900 / 5
LCM(685,140) = 19180
