Greatest Common Factor
We found the factors 25,349,430 . The biggest common factor number is the GCF number.
So the greatest common factor 25,349,430 is 1.
Lets's calculate LCM of 39,20,266
2 | 39, 20, 266 |
39, 10, 133 |
∴ So the LCM of the given numbers is 2 x 39 x 10 x 133 = 103740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/103740
Therefore, the GCF of Fractions 25/39,349/20,430/266 is 1/103740
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 39,20,266 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,20,266) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(39,20,266) x common factors =1 x 2 = 2
LCM(39,20,266) = ( 39 × 20 × 266 ) / 2
LCM(39,20,266) = 207480 / 2
LCM(39,20,266) = 103740
