Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 18/47,23/54,489/631
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 18,23,489
Greatest Common Factor of Numerators i.e. GCF of 18,23,489 is 1 .
LCM of Denominators means LCM of 47,54,631 as per the given fractions.
LCM of 47,54,631 is 1601478 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 18,23,489
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 18
List of positive integer factors of 18 that divides 18 without a remainder.
1,2,3,6,9,18
Factors of 23
List of positive integer factors of 23 that divides 23 without a remainder.
1,23
Factors of 489
List of positive integer factors of 489 that divides 489 without a remainder.
1,3,163,489
Greatest Common Factor
We found the factors 18,23,489 . The biggest common factor number is the GCF number.
So the greatest common factor 18,23,489 is 1.
Lets's calculate LCM of 47,54,631
Given numbers has no common factors except 1. So, there LCM is their product i.e 1601478
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1601478
Therefore, the GCF of Fractions 18/47,23/54,489/631 is 1/1601478
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 47,54,631 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,54,631) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(47,54,631) x common factors =1 x 1 = 1
LCM(47,54,631) = ( 47 × 54 × 631 ) / 1
LCM(47,54,631) = 1601478 / 1
LCM(47,54,631) = 1601478
Here are some samples of GCF of Fractions calculations.
