Greatest Common Factor
We found the factors 10,637,209 . The biggest common factor number is the GCF number.
So the greatest common factor 10,637,209 is 1.
Lets's calculate LCM of 13,39,440
13 | 13, 39, 440 |
1, 3, 440 |
∴ So the LCM of the given numbers is 13 x 1 x 3 x 440 = 17160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17160
Therefore, the GCF of Fractions 10/13,637/39,209/440 is 1/17160
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 13,39,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(13,39,440) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(13,39,440) x common factors =1 x 13 = 13
LCM(13,39,440) = ( 13 × 39 × 440 ) / 13
LCM(13,39,440) = 223080 / 13
LCM(13,39,440) = 17160
