Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 79/15,27/23,505/30
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 79,27,505
Greatest Common Factor of Numerators i.e. GCF of 79,27,505 is 1 .
LCM of Denominators means LCM of 15,23,30 as per the given fractions.
LCM of 15,23,30 is 690 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 79,27,505
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 79
List of positive integer factors of 79 that divides 79 without a remainder.
1,79
Factors of 27
List of positive integer factors of 27 that divides 27 without a remainder.
1,3,9,27
Factors of 505
List of positive integer factors of 505 that divides 505 without a remainder.
1,5,101,505
Greatest Common Factor
We found the factors 79,27,505 . The biggest common factor number is the GCF number.
So the greatest common factor 79,27,505 is 1.
Lets's calculate LCM of 15,23,30
3 | 15, 23, 30 |
5 | 5, 23, 10 |
1, 23, 2 |
∴ So the LCM of the given numbers is 3 x 5 x 1 x 23 x 2 = 690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/690
Therefore, the GCF of Fractions 79/15,27/23,505/30 is 1/690
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 15,23,30 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,23,30) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(15,23,30) x common factors =1 x 15 = 15
LCM(15,23,30) = ( 15 × 23 × 30 ) / 15
LCM(15,23,30) = 10350 / 15
LCM(15,23,30) = 690
