Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 38/90,89/90,385/67
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 38,89,385
Greatest Common Factor of Numerators i.e. GCF of 38,89,385 is 1 .
LCM of Denominators means LCM of 90,90,67 as per the given fractions.
LCM of 90,90,67 is 6030 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 38,89,385
∴ So GCF of numbers is 1 because of no common factors present between them.

1,89
Factors of 385
List of positive integer factors of 385 that divides 385 without a remainder.
1,5,7,11,35,55,77,385
Greatest Common Factor
We found the factors 38,89,385 . The biggest common factor number is the GCF number.
So the greatest common factor 38,89,385 is 1.
Lets's calculate LCM of 90,90,67
2 | 90, 90, 67 |
3 | 45, 45, 67 |
3 | 15, 15, 67 |
5 | 5, 5, 67 |
1, 1, 67 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 1 x 1 x 67 = 6030
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6030
Therefore, the GCF of Fractions 38/90,89/90,385/67 is 1/6030
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 90,90,67 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,90,67) = 1
common factors(in case of two or more numbers have common factors) = 90
GCF(90,90,67) x common factors =1 x 90 = 90
LCM(90,90,67) = ( 90 × 90 × 67 ) / 90
LCM(90,90,67) = 542700 / 90
LCM(90,90,67) = 6030
