Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 69/777,15/805
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 69,15
Greatest Common Factor of Numerators i.e. GCF of 69,15 is 3 .
LCM of Denominators means LCM of 777,805 as per the given fractions.
LCM of 777,805 is 89355 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 69,15
3 | 69, 15 |
23, 5 |
∴ So the GCF of the given numbers is 3 = 3
Factors of 69
List of positive integer factors of 69 that divides 69 without a remainder.
1,3,23,69
Factors of 15
List of positive integer factors of 15 that divides 15 without a remainder.
1,3,5,15
Greatest Common Factor
We found the factors 69,15 . The biggest common factor number is the GCF number.
So the greatest common factor 69,15 is 3.
Lets's calculate LCM of 777,805
7 | 777, 805 |
111, 115 |
∴ So the LCM of the given numbers is 7 x 111 x 115 = 89355
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/89355
Therefore, the GCF of Fractions 69/777,15/805 is 3/89355
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 777,805 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(777,805) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(777,805) x common factors =7 x 1 = 7
LCM(777,805) = ( 777 × 805 ) / 7
LCM(777,805) = 625485 / 7
LCM(777,805) = 89355
