Factors of 3837
List of positive integer factors of 3837 that divides 3837 without a remainder.
1,3,1279,3837
Greatest Common Factor
We found the factors 780,3837 . The biggest common factor number is the GCF number.
So the greatest common factor 780,3837 is 3.
Lets's calculate LCM of 643,632
Given numbers has no common factors except 1. So, there LCM is their product i.e 406376
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/406376
Therefore, the GCF of Fractions 780/643,3837/632 is 3/406376
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 643,632 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(643,632) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(643,632) x common factors =1 x 1 = 1
LCM(643,632) = ( 643 × 632 ) / 1
LCM(643,632) = 406376 / 1
LCM(643,632) = 406376
Here are some samples of GCF of Fractions calculations.
