Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 644/49,276/121
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 644,276
Greatest Common Factor of Numerators i.e. GCF of 644,276 is 92 .
LCM of Denominators means LCM of 49,121 as per the given fractions.
LCM of 49,121 is 5929 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 644,276
2 | 644, 276 |
2 | 322, 138 |
23 | 161, 69 |
7, 3 |
∴ So the GCF of the given numbers is 2 x 2 x 23 = 92

1,2,4,7,14,23,28,46,92,161,322,644
Factors of 276
List of positive integer factors of 276 that divides 276 without a remainder.
1,2,3,4,6,12,23,46,69,92,138,276
Greatest Common Factor
We found the factors 644,276 . The biggest common factor number is the GCF number.
So the greatest common factor 644,276 is 92.
Lets's calculate LCM of 49,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 5929
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 92/5929
Therefore, the GCF of Fractions 644/49,276/121 is 92/5929
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 49,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(49,121) x common factors =1 x 1 = 1
LCM(49,121) = ( 49 × 121 ) / 1
LCM(49,121) = 5929 / 1
LCM(49,121) = 5929
