Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 47/39,73/80,521/787
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 47,73,521
Greatest Common Factor of Numerators i.e. GCF of 47,73,521 is 1 .
LCM of Denominators means LCM of 39,80,787 as per the given fractions.
LCM of 39,80,787 is 2455440 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 47,73,521
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 47
List of positive integer factors of 47 that divides 47 without a remainder.
1,47
Factors of 73
List of positive integer factors of 73 that divides 73 without a remainder.
1,73
Factors of 521
List of positive integer factors of 521 that divides 521 without a remainder.
1,521
Greatest Common Factor
We found the factors 47,73,521 . The biggest common factor number is the GCF number.
So the greatest common factor 47,73,521 is 1.
Lets's calculate LCM of 39,80,787
Given numbers has no common factors except 1. So, there LCM is their product i.e 2455440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2455440
Therefore, the GCF of Fractions 47/39,73/80,521/787 is 1/2455440
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 39,80,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,80,787) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,80,787) x common factors =1 x 1 = 1
LCM(39,80,787) = ( 39 × 80 × 787 ) / 1
LCM(39,80,787) = 2455440 / 1
LCM(39,80,787) = 2455440
Here are some samples of GCF of Fractions calculations.
