So the greatest common factor 17,172,580 is 1.
Lets's calculate LCM of 239,406,530
2 | 239, 406, 530 |
239, 203, 265 |
∴ So the LCM of the given numbers is 2 x 239 x 203 x 265 = 25714010
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25714010
Therefore, the GCF of Fractions 17/239,172/406,580/530 is 1/25714010
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 239,406,530 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(239,406,530) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(239,406,530) x common factors =1 x 2 = 2
LCM(239,406,530) = ( 239 × 406 × 530 ) / 2
LCM(239,406,530) = 51428020 / 2
LCM(239,406,530) = 25714010
