Factors of 530
List of positive integer factors of 530 that divides 530 without a remainder.
1,2,5,10,53,106,265,530
Greatest Common Factor
We found the factors 516,530 . The biggest common factor number is the GCF number.
So the greatest common factor 516,530 is 2.
Lets's calculate LCM of 378,662
2 | 378, 662 |
189, 331 |
∴ So the LCM of the given numbers is 2 x 189 x 331 = 125118
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/125118
Therefore, the GCF of Fractions 516/378,530/662 is 2/125118
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 378,662 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(378,662) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(378,662) x common factors =2 x 1 = 2
LCM(378,662) = ( 378 × 662 ) / 2
LCM(378,662) = 250236 / 2
LCM(378,662) = 125118
