List of positive integer factors of 403 that divides 403 without a remainder.
1,13,31,403
Factors of 256
List of positive integer factors of 256 that divides 256 without a remainder.
1,2,4,8,16,32,64,128,256
Greatest Common Factor
We found the factors 13,403,256 . The biggest common factor number is the GCF number.
So the greatest common factor 13,403,256 is 1.
Lets's calculate LCM of 428,904,531
2 | 428, 904, 531 |
2 | 214, 452, 531 |
107, 226, 531 |
∴ So the LCM of the given numbers is 2 x 2 x 107 x 226 x 531 = 51362568
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/51362568
Therefore, the GCF of Fractions 13/428,403/904,256/531 is 1/51362568
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 428,904,531 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,904,531) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(428,904,531) x common factors =1 x 4 = 4
LCM(428,904,531) = ( 428 × 904 × 531 ) / 4
LCM(428,904,531) = 205450272 / 4
LCM(428,904,531) = 51362568
