Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 15/838,620/932
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 15,620
Greatest Common Factor of Numerators i.e. GCF of 15,620 is 5 .
LCM of Denominators means LCM of 838,932 as per the given fractions.
LCM of 838,932 is 390508 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 15,620
5 | 15, 620 |
3, 124 |
∴ So the GCF of the given numbers is 5 = 5
Factors of 15
List of positive integer factors of 15 that divides 15 without a remainder.
1,3,5,15
Factors of 620
List of positive integer factors of 620 that divides 620 without a remainder.
1,2,4,5,10,20,31,62,124,155,310,620
Greatest Common Factor
We found the factors 15,620 . The biggest common factor number is the GCF number.
So the greatest common factor 15,620 is 5.
Lets's calculate LCM of 838,932
2 | 838, 932 |
419, 466 |
∴ So the LCM of the given numbers is 2 x 419 x 466 = 390508
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/390508
Therefore, the GCF of Fractions 15/838,620/932 is 5/390508
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 838,932 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(838,932) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(838,932) x common factors =2 x 1 = 2
LCM(838,932) = ( 838 × 932 ) / 2
LCM(838,932) = 781016 / 2
LCM(838,932) = 390508
