Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 10/921,800/762
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 10,800
Greatest Common Factor of Numerators i.e. GCF of 10,800 is 10 .
LCM of Denominators means LCM of 921,762 as per the given fractions.
LCM of 921,762 is 233934 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 10,800
2 | 10, 800 |
5 | 5, 400 |
1, 80 |
∴ So the GCF of the given numbers is 2 x 5 = 10
Factors of 10
List of positive integer factors of 10 that divides 10 without a remainder.
1,2,5,10
Factors of 800
List of positive integer factors of 800 that divides 800 without a remainder.
1,2,4,5,8,10,16,20,25,32,40,50,80,100,160,200,400,800
Greatest Common Factor
We found the factors 10,800 . The biggest common factor number is the GCF number.
So the greatest common factor 10,800 is 10.
Lets's calculate LCM of 921,762
3 | 921, 762 |
307, 254 |
∴ So the LCM of the given numbers is 3 x 307 x 254 = 233934
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/233934
Therefore, the GCF of Fractions 10/921,800/762 is 10/233934
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 921,762 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,762) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(921,762) x common factors =3 x 1 = 3
LCM(921,762) = ( 921 × 762 ) / 3
LCM(921,762) = 701802 / 3
LCM(921,762) = 233934
