We found the factors 19,97,116 . The biggest common factor number is the GCF number.
So the greatest common factor 19,97,116 is 1.
Lets's calculate LCM of 915,585,455
3 | 915, 585, 455 |
5 | 305, 195, 455 |
13 | 61, 39, 91 |
61, 3, 7 |
∴ So the LCM of the given numbers is 3 x 5 x 13 x 61 x 3 x 7 = 249795
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/249795
Therefore, the GCF of Fractions 19/915,97/585,116/455 is 1/249795
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 915,585,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(915,585,455) = 5
common factors(in case of two or more numbers have common factors) = 195
GCF(915,585,455) x common factors =5 x 195 = 975
LCM(915,585,455) = ( 915 × 585 × 455 ) / 975
LCM(915,585,455) = 243550125 / 975
LCM(915,585,455) = 249795
