Greatest Common Factor
We found the factors 13,617,320 . The biggest common factor number is the GCF number.
So the greatest common factor 13,617,320 is 1.
Lets's calculate LCM of 39,33,957
3 | 39, 33, 957 |
11 | 13, 11, 319 |
13, 1, 29 |
∴ So the LCM of the given numbers is 3 x 11 x 13 x 1 x 29 = 12441
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12441
Therefore, the GCF of Fractions 13/39,617/33,320/957 is 1/12441
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 39,33,957 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,33,957) = 3
common factors(in case of two or more numbers have common factors) = 33
GCF(39,33,957) x common factors =3 x 33 = 99
LCM(39,33,957) = ( 39 × 33 × 957 ) / 99
LCM(39,33,957) = 1231659 / 99
LCM(39,33,957) = 12441
