Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 173/640,4090/240
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 173,4090
Greatest Common Factor of Numerators i.e. GCF of 173,4090 is 1 .
LCM of Denominators means LCM of 640,240 as per the given fractions.
LCM of 640,240 is 1920 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 173,4090
∴ So GCF of numbers is 1 because of no common factors present between them.

1,2,5,10,409,818,2045,4090
Greatest Common Factor
We found the factors 173,4090 . The biggest common factor number is the GCF number.
So the greatest common factor 173,4090 is 1.
Lets's calculate LCM of 640,240
2 | 640, 240 |
2 | 320, 120 |
2 | 160, 60 |
2 | 80, 30 |
5 | 40, 15 |
8, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 8 x 3 = 1920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1920
Therefore, the GCF of Fractions 173/640,4090/240 is 1/1920
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 640,240 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(640,240) = 80
common factors(in case of two or more numbers have common factors) = 1
GCF(640,240) x common factors =80 x 1 = 80
LCM(640,240) = ( 640 × 240 ) / 80
LCM(640,240) = 153600 / 80
LCM(640,240) = 1920
