Greatest Common Factor
We found the factors 405,7200 . The biggest common factor number is the GCF number.
So the greatest common factor 405,7200 is 45.
Lets's calculate LCM of 133,9671
19 | 133, 9671 |
7, 509 |
∴ So the LCM of the given numbers is 19 x 7 x 509 = 67697
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 45/67697
Therefore, the GCF of Fractions 405/133,7200/9671 is 45/67697
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 133,9671 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(133,9671) = 19
common factors(in case of two or more numbers have common factors) = 1
GCF(133,9671) x common factors =19 x 1 = 19
LCM(133,9671) = ( 133 × 9671 ) / 19
LCM(133,9671) = 1286243 / 19
LCM(133,9671) = 67697
