Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 693/33,1954/405
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 693,1954
Greatest Common Factor of Numerators i.e. GCF of 693,1954 is 1 .
LCM of Denominators means LCM of 33,405 as per the given fractions.
LCM of 33,405 is 4455 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 693,1954
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 693
List of positive integer factors of 693 that divides 693 without a remainder.
1,3,7,9,11,21,33,63,77,99,231,693
Factors of 1954
List of positive integer factors of 1954 that divides 1954 without a remainder.
1,2,977,1954
Greatest Common Factor
We found the factors 693,1954 . The biggest common factor number is the GCF number.
So the greatest common factor 693,1954 is 1.
Lets's calculate LCM of 33,405
3 | 33, 405 |
11, 135 |
∴ So the LCM of the given numbers is 3 x 11 x 135 = 4455
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4455
Therefore, the GCF of Fractions 693/33,1954/405 is 1/4455
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 33,405 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(33,405) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(33,405) x common factors =3 x 1 = 3
LCM(33,405) = ( 33 × 405 ) / 3
LCM(33,405) = 13365 / 3
LCM(33,405) = 4455
