Lets's calculate GCF of 273,403
13 | 273, 403 |
21, 31 |
∴ So the GCF of the given numbers is 13 = 13
Now, list down the factors of 273
:1,3,7,13,21,39,91,273
Now, list down the factors of 403
:1,13,31,403
Greatest Common Factor
We found the factors 273,403 . The biggest common factor number is the GCF number.
So the greatest common factor 273,403 is 13.
Lets's calculate LCM of 30,970
2 | 30, 970 |
5 | 15, 485 |
3, 97 |
∴ So the LCM of the given numbers is 2 x 5 x 3 x 97 = 2910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/2910
Therefore, the GCF of Fractions 273/30,403/970 is 13/2910
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 30,970 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,970) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(30,970) x common factors =10 x 1 = 10
LCM(30,970) = ( 30 × 970 ) / 10
LCM(30,970) = 29100 / 10
LCM(30,970) = 2910
