Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 4790/19,3280/105
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 4790,3280
Greatest Common Factor of Numerators i.e. GCF of 4790,3280 is 10 .
LCM of Denominators means LCM of 19,105 as per the given fractions.
LCM of 19,105 is 1995 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 4790,3280
2 | 4790, 3280 |
5 | 2395, 1640 |
479, 328 |
∴ So the GCF of the given numbers is 2 x 5 = 10

Greatest Common Factor
We found the factors 4790,3280 . The biggest common factor number is the GCF number.
So the greatest common factor 4790,3280 is 10.
Lets's calculate LCM of 19,105
Given numbers has no common factors except 1. So, there LCM is their product i.e 1995
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/1995
Therefore, the GCF of Fractions 4790/19,3280/105 is 10/1995
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 19,105 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,105) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,105) x common factors =1 x 1 = 1
LCM(19,105) = ( 19 × 105 ) / 1
LCM(19,105) = 1995 / 1
LCM(19,105) = 1995
