Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 96/78,23/91,74/54
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 96,23,74
Greatest Common Factor of Numerators i.e. GCF of 96,23,74 is 1 .
LCM of Denominators means LCM of 78,91,54 as per the given fractions.
LCM of 78,91,54 is 4914 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 96,23,74
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 96
List of positive integer factors of 96 that divides 96 without a remainder.
1,2,3,4,6,8,12,16,24,32,48,96
Factors of 23
List of positive integer factors of 23 that divides 23 without a remainder.
1,23
Factors of 74
List of positive integer factors of 74 that divides 74 without a remainder.
1,2,37,74
Greatest Common Factor
We found the factors 96,23,74 . The biggest common factor number is the GCF number.
So the greatest common factor 96,23,74 is 1.
Lets's calculate LCM of 78,91,54
2 | 78, 91, 54 |
3 | 39, 91, 27 |
13 | 13, 91, 9 |
1, 7, 9 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 7 x 9 = 4914
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4914
Therefore, the GCF of Fractions 96/78,23/91,74/54 is 1/4914
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 78,91,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,91,54) = 1
common factors(in case of two or more numbers have common factors) = 78
GCF(78,91,54) x common factors =1 x 78 = 78
LCM(78,91,54) = ( 78 × 91 × 54 ) / 78
LCM(78,91,54) = 383292 / 78
LCM(78,91,54) = 4914
