Use our free GCF of Fractions Calculator tool to compute the GCF of 9/70, 3/81, 9/73, 69/509 i.e 3/210680190 easily. The following is the detailed procedure to determine the greatest common factor of fractions 9/70, 3/81, 9/73, 69/509.
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 9/70,3/81,9/73,69/509
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 9/70,3/81,9/73,69/509, numerators are 9,3,9,69
Denominators are 70,81,73,509
The GCF of 9,3,9,69 is 3 .
LCM of 70,81,73,509 is 210680190.
The greatest common factor of 9/70,3/81,9/73,69/509 = [GCF of 9,3,9,69]/[LCM of 70,81,73,509]= 3/210680190
Therefore, the GCF of 9/70,3/81,9/73,69/509 is 3/210680190.

The factors of 9 are 1, 3, 9
The factors of 3 are 1, 3
The factors of 9 are 1, 3, 9
The factors of 69 are 1, 3, 23, 69
The HCF of 9,3,9,69 is 3.
Lets's calculate GCF of 9,3,9,69
3 | 9, 3, 9, 69 |
3, 1, 3, 23 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 9
:1,3,9
Now, list down the factors of 3
:1,3
Now, list down the factors of 9
:1,3,9
Now, list down the factors of 69
:1,3,23,69
Greatest Common Factor
We found the factors 9,3,9,69 . The biggest common factor number is the GCF number.
So the greatest common factor 9,3,9,69 is 3.
Lets's calculate LCM of 70,81,73,509
Given numbers has no common factors except 1. So, there LCM is their product i.e 210680190
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/210680190
Therefore, the GCF of Fractions 9/70,3/81,9/73,69/509 is 3/210680190
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 70,81,73,509 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,81,73,509) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(70,81,73,509) x common factors =1 x 1 = 1
LCM(70,81,73,509) = ( 70 × 81 × 73 × 509 ) / 1
LCM(70,81,73,509) = 210680190 / 1
LCM(70,81,73,509) = 210680190
