Use our free GCF of Fractions Calculator tool to compute the GCF of 3/40, 7/89, 1/19, 20/951 i.e 1/64325640 easily. The following is the detailed procedure to determine the greatest common factor of fractions 3/40, 7/89, 1/19, 20/951.
Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 3/40,7/89,1/19,20/951
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 3/40,7/89,1/19,20/951, numerators are 3,7,1,20
Denominators are 40,89,19,951
The GCF of 3,7,1,20 is 1 .
LCM of 40,89,19,951 is 64325640.
The greatest common factor of 3/40,7/89,1/19,20/951 = [GCF of 3,7,1,20]/[LCM of 40,89,19,951]= 1/64325640
Therefore, the GCF of 3/40,7/89,1/19,20/951 is 1/64325640.
To find the highest common factor of 3,7,1,20, we have to find the factors of both numbers and list the highest common factor.
The factors of 3 are 1, 3
The factors of 7 are 1, 7
The factors of 1 are 1
The factors of 20 are 1, 2, 4, 5, 10, 20
The HCF of 3,7,1,20 is 1.
Lets's calculate GCF of 3,7,1,20
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 3
:1,3
Now, list down the factors of 7
:1,7
Now, list down the factors of 1
:1
Now, list down the factors of 20
:1,2,4,5,10,20
Greatest Common Factor
We found the factors 3,7,1,20 . The biggest common factor number is the GCF number.
So the greatest common factor 3,7,1,20 is 1.
Lets's calculate LCM of 40,89,19,951
Given numbers has no common factors except 1. So, there LCM is their product i.e 64325640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/64325640
Therefore, the GCF of Fractions 3/40,7/89,1/19,20/951 is 1/64325640
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 40,89,19,951 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,89,19,951) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(40,89,19,951) x common factors =1 x 1 = 1
LCM(40,89,19,951) = ( 40 × 89 × 19 × 951 ) / 1
LCM(40,89,19,951) = 64325640 / 1
LCM(40,89,19,951) = 64325640
