Greatest Common Factor
We found the factors 80,13,479 . The biggest common factor number is the GCF number.
So the greatest common factor 80,13,479 is 1.
Lets's calculate LCM of 311,670,498
2 | 311, 670, 498 |
311, 335, 249 |
∴ So the LCM of the given numbers is 2 x 311 x 335 x 249 = 51884130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/51884130
Therefore, the GCF of Fractions 80/311,13/670,479/498 is 1/51884130
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 311,670,498 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(311,670,498) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(311,670,498) x common factors =1 x 2 = 2
LCM(311,670,498) = ( 311 × 670 × 498 ) / 2
LCM(311,670,498) = 103768260 / 2
LCM(311,670,498) = 51884130
