Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 858/483,245/756
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 858,245
Greatest Common Factor of Numerators i.e. GCF of 858,245 is 1 .
LCM of Denominators means LCM of 483,756 as per the given fractions.
LCM of 483,756 is 17388 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 858,245
∴ So GCF of numbers is 1 because of no common factors present between them.

1,5,7,35,49,245
Greatest Common Factor
We found the factors 858,245 . The biggest common factor number is the GCF number.
So the greatest common factor 858,245 is 1.
Lets's calculate LCM of 483,756
3 | 483, 756 |
7 | 161, 252 |
23, 36 |
∴ So the LCM of the given numbers is 3 x 7 x 23 x 36 = 17388
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17388
Therefore, the GCF of Fractions 858/483,245/756 is 1/17388
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 483,756 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(483,756) = 21
common factors(in case of two or more numbers have common factors) = 1
GCF(483,756) x common factors =21 x 1 = 21
LCM(483,756) = ( 483 × 756 ) / 21
LCM(483,756) = 365148 / 21
LCM(483,756) = 17388
