Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 820/90,285/4029
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 820,285
Greatest Common Factor of Numerators i.e. GCF of 820,285 is 5 .
LCM of Denominators means LCM of 90,4029 as per the given fractions.
LCM of 90,4029 is 120870 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 820,285
5 | 820, 285 |
164, 57 |
∴ So the GCF of the given numbers is 5 = 5

1,3,5,15,19,57,95,285
Greatest Common Factor
We found the factors 820,285 . The biggest common factor number is the GCF number.
So the greatest common factor 820,285 is 5.
Lets's calculate LCM of 90,4029
3 | 90, 4029 |
30, 1343 |
∴ So the LCM of the given numbers is 3 x 30 x 1343 = 120870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/120870
Therefore, the GCF of Fractions 820/90,285/4029 is 5/120870
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 90,4029 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,4029) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(90,4029) x common factors =3 x 1 = 3
LCM(90,4029) = ( 90 × 4029 ) / 3
LCM(90,4029) = 362610 / 3
LCM(90,4029) = 120870
