Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 970/455,965/538
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 970,965
Greatest Common Factor of Numerators i.e. GCF of 970,965 is 5 .
LCM of Denominators means LCM of 455,538 as per the given fractions.
LCM of 455,538 is 244790 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 970,965
5 | 970, 965 |
194, 193 |
∴ So the GCF of the given numbers is 5 = 5

Factors of 965
List of positive integer factors of 965 that divides 965 without a remainder.
1,5,193,965
Greatest Common Factor
We found the factors 970,965 . The biggest common factor number is the GCF number.
So the greatest common factor 970,965 is 5.
Lets's calculate LCM of 455,538
Given numbers has no common factors except 1. So, there LCM is their product i.e 244790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/244790
Therefore, the GCF of Fractions 970/455,965/538 is 5/244790
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 455,538 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(455,538) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(455,538) x common factors =1 x 1 = 1
LCM(455,538) = ( 455 × 538 ) / 1
LCM(455,538) = 244790 / 1
LCM(455,538) = 244790
