Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 24/39,29/31,749/69
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 24,29,749
Greatest Common Factor of Numerators i.e. GCF of 24,29,749 is 1 .
LCM of Denominators means LCM of 39,31,69 as per the given fractions.
LCM of 39,31,69 is 27807 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 24,29,749
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 24

1,29
Factors of 749
List of positive integer factors of 749 that divides 749 without a remainder.
1,7,107,749
Greatest Common Factor
We found the factors 24,29,749 . The biggest common factor number is the GCF number.
So the greatest common factor 24,29,749 is 1.
Lets's calculate LCM of 39,31,69
3 | 39, 31, 69 |
13, 31, 23 |
∴ So the LCM of the given numbers is 3 x 13 x 31 x 23 = 27807
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/27807
Therefore, the GCF of Fractions 24/39,29/31,749/69 is 1/27807
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 39,31,69 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,31,69) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(39,31,69) x common factors =1 x 3 = 3
LCM(39,31,69) = ( 39 × 31 × 69 ) / 3
LCM(39,31,69) = 83421 / 3
LCM(39,31,69) = 27807
