1,17,41,697
Greatest Common Factor
We found the factors 660,921,697 . The biggest common factor number is the GCF number.
So the greatest common factor 660,921,697 is 1.
Lets's calculate LCM of 90,86,810
2 | 90, 86, 810 |
3 | 45, 43, 405 |
3 | 15, 43, 135 |
5 | 5, 43, 45 |
1, 43, 9 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 1 x 43 x 9 = 34830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34830
Therefore, the GCF of Fractions 660/90,921/86,697/810 is 1/34830
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 90,86,810 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,86,810) = 2
common factors(in case of two or more numbers have common factors) = 90
GCF(90,86,810) x common factors =2 x 90 = 180
LCM(90,86,810) = ( 90 × 86 × 810 ) / 180
LCM(90,86,810) = 6269400 / 180
LCM(90,86,810) = 34830
