Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 25/19,40/88,261/766
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 25,40,261
Greatest Common Factor of Numerators i.e. GCF of 25,40,261 is 1 .
LCM of Denominators means LCM of 19,88,766 as per the given fractions.
LCM of 19,88,766 is 640376 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 25,40,261
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 25

1,5,25
Factors of 40
List of positive integer factors of 40 that divides 40 without a remainder.
1,2,4,5,8,10,20,40
Factors of 261
List of positive integer factors of 261 that divides 261 without a remainder.
1,3,9,29,87,261
Greatest Common Factor
We found the factors 25,40,261 . The biggest common factor number is the GCF number.
So the greatest common factor 25,40,261 is 1.
Lets's calculate LCM of 19,88,766
2 | 19, 88, 766 |
19, 44, 383 |
∴ So the LCM of the given numbers is 2 x 19 x 44 x 383 = 640376
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/640376
Therefore, the GCF of Fractions 25/19,40/88,261/766 is 1/640376
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 19,88,766 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,88,766) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(19,88,766) x common factors =1 x 2 = 2
LCM(19,88,766) = ( 19 × 88 × 766 ) / 2
LCM(19,88,766) = 1280752 / 2
LCM(19,88,766) = 640376
