Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 31/85,15/64,431/340
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 31,15,431
Greatest Common Factor of Numerators i.e. GCF of 31,15,431 is 1 .
LCM of Denominators means LCM of 85,64,340 as per the given fractions.
LCM of 85,64,340 is 5440 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 31,15,431
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 31
List of positive integer factors of 31 that divides 31 without a remainder.
1,31
Factors of 15
List of positive integer factors of 15 that divides 15 without a remainder.
1,3,5,15
Factors of 431
List of positive integer factors of 431 that divides 431 without a remainder.
1,431
Greatest Common Factor
We found the factors 31,15,431 . The biggest common factor number is the GCF number.
So the greatest common factor 31,15,431 is 1.
Lets's calculate LCM of 85,64,340
2 | 85, 64, 340 |
2 | 85, 32, 170 |
5 | 85, 16, 85 |
17 | 17, 16, 17 |
1, 16, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 17 x 1 x 16 x 1 = 5440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5440
Therefore, the GCF of Fractions 31/85,15/64,431/340 is 1/5440
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 85,64,340 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,64,340) = 1
common factors(in case of two or more numbers have common factors) = 340
GCF(85,64,340) x common factors =1 x 340 = 340
LCM(85,64,340) = ( 85 × 64 × 340 ) / 340
LCM(85,64,340) = 1849600 / 340
LCM(85,64,340) = 5440
