Greatest Common Factor
We found the factors 33,15,308 . The biggest common factor number is the GCF number.
So the greatest common factor 33,15,308 is 1.
Lets's calculate LCM of 455,730,409
5 | 455, 730, 409 |
91, 146, 409 |
∴ So the LCM of the given numbers is 5 x 91 x 146 x 409 = 27169870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/27169870
Therefore, the GCF of Fractions 33/455,15/730,308/409 is 1/27169870
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 455,730,409 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(455,730,409) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(455,730,409) x common factors =1 x 5 = 5
LCM(455,730,409) = ( 455 × 730 × 409 ) / 5
LCM(455,730,409) = 135849350 / 5
LCM(455,730,409) = 27169870
