Use our free GCF of Fractions Calculator tool to compute the GCF of 9/431, 9/420 i.e 9/181020 easily. The following is the detailed procedure to determine the greatest common factor of fractions 9/431, 9/420.
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 9/431,9/420
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 9/431,9/420, numerators are 9,9
Denominators are 431,420
The GCF of 9,9 is 9 .
LCM of 431,420 is 181020.
The greatest common factor of 9/431,9/420 = [GCF of 9,9]/[LCM of 431,420]= 9/181020
Therefore, the GCF of 9/431,9/420 is 9/181020.
To find the highest common factor of 9,9, 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 9 are 1, 3, 9
The HCF of 9,9 is 9.
Lets's calculate GCF of 9,9
3 | 9, 9 |
3 | 3, 3 |
1, 1 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Lets's calculate LCM of 431,420
Given numbers has no common factors except 1. So, there LCM is their product i.e 181020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/181020
Therefore, the GCF of Fractions 9/431,9/420 is 9/181020
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 431,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(431,420) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(431,420) x common factors =1 x 1 = 1
LCM(431,420) = ( 431 × 420 ) / 1
LCM(431,420) = 181020 / 1
LCM(431,420) = 181020
