Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 1/420,55/397,13/397
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 1,55,13
Greatest Common Factor of Numerators i.e. GCF of 1,55,13 is 1 .
LCM of Denominators means LCM of 420,397,397 as per the given fractions.
LCM of 420,397,397 is 166740 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 1,55,13
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 1
List of positive integer factors of 1 that divides 1 without a remainder.
1
Factors of 55
List of positive integer factors of 55 that divides 55 without a remainder.
1,5,11,55
Factors of 13
List of positive integer factors of 13 that divides 13 without a remainder.
1,13
Greatest Common Factor
We found the factors 1,55,13 . The biggest common factor number is the GCF number.
So the greatest common factor 1,55,13 is 1.
Lets's calculate LCM of 420,397,397
397 | 420, 397, 397 |
420, 1, 1 |
∴ So the LCM of the given numbers is 397 x 420 x 1 x 1 = 166740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/166740
Therefore, the GCF of Fractions 1/420,55/397,13/397 is 1/166740
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 420,397,397 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,397,397) = 1
common factors(in case of two or more numbers have common factors) = 397
GCF(420,397,397) x common factors =1 x 397 = 397
LCM(420,397,397) = ( 420 × 397 × 397 ) / 397
LCM(420,397,397) = 66195780 / 397
LCM(420,397,397) = 166740
