Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 80/351,272/308
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 80,272
Greatest Common Factor of Numerators i.e. GCF of 80,272 is 16 .
LCM of Denominators means LCM of 351,308 as per the given fractions.
LCM of 351,308 is 108108 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 80,272
2 | 80, 272 |
2 | 40, 136 |
2 | 20, 68 |
2 | 10, 34 |
5, 17 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 = 16

1,2,4,5,8,10,16,20,40,80
Factors of 272
List of positive integer factors of 272 that divides 272 without a remainder.
1,2,4,8,16,17,34,68,136,272
Greatest Common Factor
We found the factors 80,272 . The biggest common factor number is the GCF number.
So the greatest common factor 80,272 is 16.
Lets's calculate LCM of 351,308
Given numbers has no common factors except 1. So, there LCM is their product i.e 108108
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/108108
Therefore, the GCF of Fractions 80/351,272/308 is 16/108108
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 351,308 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(351,308) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(351,308) x common factors =1 x 1 = 1
LCM(351,308) = ( 351 × 308 ) / 1
LCM(351,308) = 108108 / 1
LCM(351,308) = 108108
