Factors of 1129
List of positive integer factors of 1129 that divides 1129 without a remainder.
1,1129
Greatest Common Factor
We found the factors 761,1129 . The biggest common factor number is the GCF number.
So the greatest common factor 761,1129 is 1.
Lets's calculate LCM of 393,693
3 | 393, 693 |
131, 231 |
∴ So the LCM of the given numbers is 3 x 131 x 231 = 90783
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/90783
Therefore, the GCF of Fractions 761/393,1129/693 is 1/90783
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 393,693 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(393,693) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(393,693) x common factors =3 x 1 = 3
LCM(393,693) = ( 393 × 693 ) / 3
LCM(393,693) = 272349 / 3
LCM(393,693) = 90783
