Greatest Common Factor
We found the factors 47,821,656 . The biggest common factor number is the GCF number.
So the greatest common factor 47,821,656 is 1.
Lets's calculate LCM of 85,17,291
17 | 85, 17, 291 |
5, 1, 291 |
∴ So the LCM of the given numbers is 17 x 5 x 1 x 291 = 24735
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/24735
Therefore, the GCF of Fractions 47/85,821/17,656/291 is 1/24735
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 85,17,291 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,17,291) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(85,17,291) x common factors =1 x 17 = 17
LCM(85,17,291) = ( 85 × 17 × 291 ) / 17
LCM(85,17,291) = 420495 / 17
LCM(85,17,291) = 24735
