Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 14/47,28/69,16/69,73/12
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 14,28,16,73
Greatest Common Factor of Numerators i.e. GCF of 14,28,16,73 is 1 .
LCM of Denominators means LCM of 47,69,69,12 as per the given fractions.
LCM of 47,69,69,12 is 12972 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 14,28,16,73
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 14
List of positive integer factors of 14 that divides 14 without a remainder.
1,2,7,14
Factors of 28
List of positive integer factors of 28 that divides 28 without a remainder.
1,2,4,7,14,28
Factors of 16
List of positive integer factors of 16 that divides 16 without a remainder.
1,2,4,8,16
Factors of 73
List of positive integer factors of 73 that divides 73 without a remainder.
1,73
Greatest Common Factor
We found the factors 14,28,16,73 . The biggest common factor number is the GCF number.
So the greatest common factor 14,28,16,73 is 1.
Lets's calculate LCM of 47,69,69,12
3 | 47, 69, 69, 12 |
23 | 47, 23, 23, 4 |
47, 1, 1, 4 |
∴ So the LCM of the given numbers is 3 x 23 x 47 x 1 x 1 x 4 = 12972
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12972
Therefore, the GCF of Fractions 14/47,28/69,16/69,73/12 is 1/12972
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 47,69,69,12 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,69,69,12) = 1
common factors(in case of two or more numbers have common factors) = 207
GCF(47,69,69,12) x common factors =1 x 207 = 207
LCM(47,69,69,12) = ( 47 × 69 × 69 × 12 ) / 207
LCM(47,69,69,12) = 2685204 / 207
LCM(47,69,69,12) = 12972
