Lets's calculate GCF of 450,675
3 | 450, 675 |
3 | 150, 225 |
5 | 50, 75 |
5 | 10, 15 |
2, 3 |
∴ So the GCF of the given numbers is 3 x 3 x 5 x 5 = 225
Now, list down the factors of 450
:1,2,3,5,6,9,10,15,18,25,30,45,50,75,90,150,225,450
Now, list down the factors of 675
:1,3,5,9,15,25,27,45,75,135,225,675
Greatest Common Factor
We found the factors 450,675 . The biggest common factor number is the GCF number.
So the greatest common factor 450,675 is 225.
Lets's calculate LCM of 91,809
Given numbers has no common factors except 1. So, there LCM is their product i.e 73619
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 225/73619
Therefore, the GCF of Fractions 450/91,675/809 is 225/73619
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 91,809 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,809) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,809) x common factors =1 x 1 = 1
LCM(91,809) = ( 91 × 809 ) / 1
LCM(91,809) = 73619 / 1
LCM(91,809) = 73619
