Greatest Common Factor
We found the factors 99,36,98,69 . The biggest common factor number is the GCF number.
So the greatest common factor 99,36,98,69 is 1.
Lets's calculate LCM of 35,27,72,83
3 | 35, 27, 72, 83 |
3 | 35, 9, 24, 83 |
35, 3, 8, 83 |
∴ So the LCM of the given numbers is 3 x 3 x 35 x 3 x 8 x 83 = 627480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/627480
Therefore, the GCF of Fractions 99/35,36/27,98/72,69/83 is 1/627480
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 35,27,72,83 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,27,72,83) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(35,27,72,83) x common factors =1 x 9 = 9
LCM(35,27,72,83) = ( 35 × 27 × 72 × 83 ) / 9
LCM(35,27,72,83) = 5647320 / 9
LCM(35,27,72,83) = 627480
