Factors of 687
List of positive integer factors of 687 that divides 687 without a remainder.
1,3,229,687
Greatest Common Factor
We found the factors 504,687 . The biggest common factor number is the GCF number.
So the greatest common factor 504,687 is 3.
Lets's calculate LCM of 28,3971
Given numbers has no common factors except 1. So, there LCM is their product i.e 111188
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/111188
Therefore, the GCF of Fractions 504/28,687/3971 is 3/111188
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 28,3971 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,3971) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(28,3971) x common factors =1 x 1 = 1
LCM(28,3971) = ( 28 × 3971 ) / 1
LCM(28,3971) = 111188 / 1
LCM(28,3971) = 111188
Here are some samples of GCF of Fractions calculations.
