So the greatest common factor 709,798,369 is 1.
Lets's calculate LCM of 31,81,15
3 | 31, 81, 15 |
31, 27, 5 |
∴ So the LCM of the given numbers is 3 x 31 x 27 x 5 = 12555
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12555
Therefore, the GCF of Fractions 709/31,798/81,369/15 is 1/12555
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 31,81,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,81,15) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(31,81,15) x common factors =1 x 3 = 3
LCM(31,81,15) = ( 31 × 81 × 15 ) / 3
LCM(31,81,15) = 37665 / 3
LCM(31,81,15) = 12555
