1,2,3,4,6,7,9,12,14,18,21,28,36,42,63,84,126,252
Greatest Common Factor
We found the factors 90,91,252 . The biggest common factor number is the GCF number.
So the greatest common factor 90,91,252 is 1.
Lets's calculate LCM of 408,858,911
2 | 408, 858, 911 |
3 | 204, 429, 911 |
68, 143, 911 |
∴ So the LCM of the given numbers is 2 x 3 x 68 x 143 x 911 = 53151384
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/53151384
Therefore, the GCF of Fractions 90/408,91/858,252/911 is 1/53151384
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 408,858,911 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(408,858,911) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(408,858,911) x common factors =1 x 6 = 6
LCM(408,858,911) = ( 408 × 858 × 911 ) / 6
LCM(408,858,911) = 318908304 / 6
LCM(408,858,911) = 53151384
