Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 549/97,189/1029
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 549,189
Greatest Common Factor of Numerators i.e. GCF of 549,189 is 9 .
LCM of Denominators means LCM of 97,1029 as per the given fractions.
LCM of 97,1029 is 99813 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 549,189
3 | 549, 189 |
3 | 183, 63 |
61, 21 |
∴ So the GCF of the given numbers is 3 x 3 = 9

1,3,9,61,183,549
Factors of 189
List of positive integer factors of 189 that divides 189 without a remainder.
1,3,7,9,21,27,63,189
Greatest Common Factor
We found the factors 549,189 . The biggest common factor number is the GCF number.
So the greatest common factor 549,189 is 9.
Lets's calculate LCM of 97,1029
Given numbers has no common factors except 1. So, there LCM is their product i.e 99813
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/99813
Therefore, the GCF of Fractions 549/97,189/1029 is 9/99813
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 97,1029 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,1029) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,1029) x common factors =1 x 1 = 1
LCM(97,1029) = ( 97 × 1029 ) / 1
LCM(97,1029) = 99813 / 1
LCM(97,1029) = 99813
