Factors of 2828
List of positive integer factors of 2828 that divides 2828 without a remainder.
1,2,4,7,14,28,101,202,404,707,1414,2828
Greatest Common Factor
We found the factors 689,2828 . The biggest common factor number is the GCF number.
So the greatest common factor 689,2828 is 1.
Lets's calculate LCM of 949,451
Given numbers has no common factors except 1. So, there LCM is their product i.e 427999
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/427999
Therefore, the GCF of Fractions 689/949,2828/451 is 1/427999
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 949,451 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(949,451) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(949,451) x common factors =1 x 1 = 1
LCM(949,451) = ( 949 × 451 ) / 1
LCM(949,451) = 427999 / 1
LCM(949,451) = 427999
