Factors of 502
List of positive integer factors of 502 that divides 502 without a remainder.
1,2,251,502
Greatest Common Factor
We found the factors 990,797,502 . The biggest common factor number is the GCF number.
So the greatest common factor 990,797,502 is 1.
Lets's calculate LCM of 16,21,814
2 | 16, 21, 814 |
8, 21, 407 |
∴ So the LCM of the given numbers is 2 x 8 x 21 x 407 = 136752
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/136752
Therefore, the GCF of Fractions 990/16,797/21,502/814 is 1/136752
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 16,21,814 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,21,814) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(16,21,814) x common factors =1 x 2 = 2
LCM(16,21,814) = ( 16 × 21 × 814 ) / 2
LCM(16,21,814) = 273504 / 2
LCM(16,21,814) = 136752
