Use our free GCF of Fractions Calculator tool to compute the GCF of 9/10, 31/401, 56/387 i.e 1/1551870 easily. The following is the detailed procedure to determine the greatest common factor of fractions 9/10, 31/401, 56/387.
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 9/10,31/401,56/387
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 9/10,31/401,56/387, numerators are 9,31,56
Denominators are 10,401,387
The GCF of 9,31,56 is 1 .
LCM of 10,401,387 is 1551870.
The greatest common factor of 9/10,31/401,56/387 = [GCF of 9,31,56]/[LCM of 10,401,387]= 1/1551870
Therefore, the GCF of 9/10,31/401,56/387 is 1/1551870.
To find the highest common factor of 9,31,56, we have to find the factors of both numbers and list the highest common factor.
The factors of 9 are 1, 3, 9
The factors of 31 are 1, 31
The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56
The HCF of 9,31,56 is 1.
Lets's calculate GCF of 9,31,56
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 9
:1,3,9
Now, list down the factors of 31
:1,31
Now, list down the factors of 56
:1,2,4,7,8,14,28,56
Greatest Common Factor
We found the factors 9,31,56 . The biggest common factor number is the GCF number.
So the greatest common factor 9,31,56 is 1.
Lets's calculate LCM of 10,401,387
Given numbers has no common factors except 1. So, there LCM is their product i.e 1551870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1551870
Therefore, the GCF of Fractions 9/10,31/401,56/387 is 1/1551870
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 10,401,387 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,401,387) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(10,401,387) x common factors =1 x 1 = 1
LCM(10,401,387) = ( 10 × 401 × 387 ) / 1
LCM(10,401,387) = 1551870 / 1
LCM(10,401,387) = 1551870
