1,991
Factors of 405
List of positive integer factors of 405 that divides 405 without a remainder.
1,3,5,9,15,27,45,81,135,405
Greatest Common Factor
We found the factors 21,991,405 . The biggest common factor number is the GCF number.
So the greatest common factor 21,991,405 is 1.
Lets's calculate LCM of 959,297,341
11 | 959, 297, 341 |
959, 27, 31 |
∴ So the LCM of the given numbers is 11 x 959 x 27 x 31 = 8829513
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8829513
Therefore, the GCF of Fractions 21/959,991/297,405/341 is 1/8829513
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 959,297,341 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(959,297,341) = 1
common factors(in case of two or more numbers have common factors) = 11
GCF(959,297,341) x common factors =1 x 11 = 11
LCM(959,297,341) = ( 959 × 297 × 341 ) / 11
LCM(959,297,341) = 97124643 / 11
LCM(959,297,341) = 8829513
