Greatest Common Factor
We found the factors 39,513,707 . The biggest common factor number is the GCF number.
So the greatest common factor 39,513,707 is 1.
Lets's calculate LCM of 65,90,806
2 | 65, 90, 806 |
5 | 65, 45, 403 |
13 | 13, 9, 403 |
1, 9, 31 |
∴ So the LCM of the given numbers is 2 x 5 x 13 x 1 x 9 x 31 = 36270
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/36270
Therefore, the GCF of Fractions 39/65,513/90,707/806 is 1/36270
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 65,90,806 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,90,806) = 1
common factors(in case of two or more numbers have common factors) = 130
GCF(65,90,806) x common factors =1 x 130 = 130
LCM(65,90,806) = ( 65 × 90 × 806 ) / 130
LCM(65,90,806) = 4715100 / 130
LCM(65,90,806) = 36270
