Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 978/161,428/579
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 978,428
Greatest Common Factor of Numerators i.e. GCF of 978,428 is 2 .
LCM of Denominators means LCM of 161,579 as per the given fractions.
LCM of 161,579 is 93219 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 978,428
2 | 978, 428 |
489, 214 |
∴ So the GCF of the given numbers is 2 = 2

Factors of 428
List of positive integer factors of 428 that divides 428 without a remainder.
1,2,4,107,214,428
Greatest Common Factor
We found the factors 978,428 . The biggest common factor number is the GCF number.
So the greatest common factor 978,428 is 2.
Lets's calculate LCM of 161,579
Given numbers has no common factors except 1. So, there LCM is their product i.e 93219
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/93219
Therefore, the GCF of Fractions 978/161,428/579 is 2/93219
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 161,579 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(161,579) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(161,579) x common factors =1 x 1 = 1
LCM(161,579) = ( 161 × 579 ) / 1
LCM(161,579) = 93219 / 1
LCM(161,579) = 93219
