:1,11,17,187
Now, list down the factors of 145
:1,5,29,145
Greatest Common Factor
We found the factors 187,145 . The biggest common factor number is the GCF number.
So the greatest common factor 187,145 is 1.
Lets's calculate LCM of 203,721
7 | 203, 721 |
29, 103 |
∴ So the LCM of the given numbers is 7 x 29 x 103 = 20909
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20909
Therefore, the GCF of Fractions 187/203,145/721 is 1/20909
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 203,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(203,721) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(203,721) x common factors =7 x 1 = 7
LCM(203,721) = ( 203 × 721 ) / 7
LCM(203,721) = 146363 / 7
LCM(203,721) = 20909
