Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 550/689,494/109
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 550,494
Greatest Common Factor of Numerators i.e. GCF of 550,494 is 2 .
LCM of Denominators means LCM of 689,109 as per the given fractions.
LCM of 689,109 is 75101 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 550,494
2 | 550, 494 |
275, 247 |
∴ So the GCF of the given numbers is 2 = 2

1,2,13,19,26,38,247,494
Greatest Common Factor
We found the factors 550,494 . The biggest common factor number is the GCF number.
So the greatest common factor 550,494 is 2.
Lets's calculate LCM of 689,109
Given numbers has no common factors except 1. So, there LCM is their product i.e 75101
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/75101
Therefore, the GCF of Fractions 550/689,494/109 is 2/75101
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 689,109 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,109) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,109) x common factors =1 x 1 = 1
LCM(689,109) = ( 689 × 109 ) / 1
LCM(689,109) = 75101 / 1
LCM(689,109) = 75101
