Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 806/440,222/720
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 806,222
Greatest Common Factor of Numerators i.e. GCF of 806,222 is 2 .
LCM of Denominators means LCM of 440,720 as per the given fractions.
LCM of 440,720 is 7920 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 806,222
2 | 806, 222 |
403, 111 |
∴ So the GCF of the given numbers is 2 = 2

1,2,3,6,37,74,111,222
Greatest Common Factor
We found the factors 806,222 . The biggest common factor number is the GCF number.
So the greatest common factor 806,222 is 2.
Lets's calculate LCM of 440,720
2 | 440, 720 |
2 | 220, 360 |
2 | 110, 180 |
5 | 55, 90 |
11, 18 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 11 x 18 = 7920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/7920
Therefore, the GCF of Fractions 806/440,222/720 is 2/7920
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 440,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(440,720) = 40
common factors(in case of two or more numbers have common factors) = 1
GCF(440,720) x common factors =40 x 1 = 40
LCM(440,720) = ( 440 × 720 ) / 40
LCM(440,720) = 316800 / 40
LCM(440,720) = 7920
