Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 310/630,230/368
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 310,230
Greatest Common Factor of Numerators i.e. GCF of 310,230 is 10 .
LCM of Denominators means LCM of 630,368 as per the given fractions.
LCM of 630,368 is 115920 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 310,230
2 | 310, 230 |
5 | 155, 115 |
31, 23 |
∴ So the GCF of the given numbers is 2 x 5 = 10

1,2,5,10,23,46,115,230
Greatest Common Factor
We found the factors 310,230 . The biggest common factor number is the GCF number.
So the greatest common factor 310,230 is 10.
Lets's calculate LCM of 630,368
2 | 630, 368 |
315, 184 |
∴ So the LCM of the given numbers is 2 x 315 x 184 = 115920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/115920
Therefore, the GCF of Fractions 310/630,230/368 is 10/115920
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 630,368 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(630,368) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(630,368) x common factors =2 x 1 = 2
LCM(630,368) = ( 630 × 368 ) / 2
LCM(630,368) = 231840 / 2
LCM(630,368) = 115920
