5 | 275, 90 |
55, 18 |
∴ So the GCF of the given numbers is 3 x 5 = 15
Now, list down the factors of 825
:1,3,5,11,15,25,33,55,75,165,275,825
Now, list down the factors of 270
:1,2,3,5,6,9,10,15,18,27,30,45,54,90,135,270
Greatest Common Factor
We found the factors 825,270 . The biggest common factor number is the GCF number.
So the greatest common factor 825,270 is 15.
Lets's calculate LCM of 12,402
2 | 12, 402 |
3 | 6, 201 |
2, 67 |
∴ So the LCM of the given numbers is 2 x 3 x 2 x 67 = 804
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/804
Therefore, the GCF of Fractions 825/12,270/402 is 15/804
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 12,402 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,402) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(12,402) x common factors =6 x 1 = 6
LCM(12,402) = ( 12 × 402 ) / 6
LCM(12,402) = 4824 / 6
LCM(12,402) = 804
