Use our free GCF of Fractions Calculator tool to compute the GCF of 8/30, 4/16, 7/31, 86/614 i.e 1/2284080 easily. The following is the detailed procedure to determine the greatest common factor of fractions 8/30, 4/16, 7/31, 86/614.
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 8/30,4/16,7/31,86/614
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 8/30,4/16,7/31,86/614, numerators are 8,4,7,86
Denominators are 30,16,31,614
The GCF of 8,4,7,86 is 1 .
LCM of 30,16,31,614 is 2284080.
The greatest common factor of 8/30,4/16,7/31,86/614 = [GCF of 8,4,7,86]/[LCM of 30,16,31,614]= 1/2284080
Therefore, the GCF of 8/30,4/16,7/31,86/614 is 1/2284080.
To find the highest common factor of 8,4,7,86, we have to find the factors of both numbers and list the highest common factor.
The factors of 8 are 1, 2, 4, 8
The factors of 4 are 1, 2, 4
The factors of 7 are 1, 7
The factors of 86 are 1, 2, 43, 86
The HCF of 8,4,7,86 is 1.
Lets's calculate GCF of 8,4,7,86
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 8
:1,2,4,8
Now, list down the factors of 4
:1,2,4
Now, list down the factors of 7
:1,7
Now, list down the factors of 86
:1,2,43,86
Greatest Common Factor
We found the factors 8,4,7,86 . The biggest common factor number is the GCF number.
So the greatest common factor 8,4,7,86 is 1.
Lets's calculate LCM of 30,16,31,614
2 | 30, 16, 31, 614 |
15, 8, 31, 307 |
∴ So the LCM of the given numbers is 2 x 15 x 8 x 31 x 307 = 2284080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2284080
Therefore, the GCF of Fractions 8/30,4/16,7/31,86/614 is 1/2284080
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 30,16,31,614 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,16,31,614) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(30,16,31,614) x common factors =1 x 4 = 4
LCM(30,16,31,614) = ( 30 × 16 × 31 × 614 ) / 4
LCM(30,16,31,614) = 9136320 / 4
LCM(30,16,31,614) = 2284080
