Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 17/99,74/35,202/61
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 17,74,202
Greatest Common Factor of Numerators i.e. GCF of 17,74,202 is 1 .
LCM of Denominators means LCM of 99,35,61 as per the given fractions.
LCM of 99,35,61 is 211365 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 17,74,202
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 17
List of positive integer factors of 17 that divides 17 without a remainder.
1,17
Factors of 74
List of positive integer factors of 74 that divides 74 without a remainder.
1,2,37,74
Factors of 202
List of positive integer factors of 202 that divides 202 without a remainder.
1,2,101,202
Greatest Common Factor
We found the factors 17,74,202 . The biggest common factor number is the GCF number.
So the greatest common factor 17,74,202 is 1.
Lets's calculate LCM of 99,35,61
Given numbers has no common factors except 1. So, there LCM is their product i.e 211365
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/211365
Therefore, the GCF of Fractions 17/99,74/35,202/61 is 1/211365
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 99,35,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,35,61) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(99,35,61) x common factors =1 x 1 = 1
LCM(99,35,61) = ( 99 × 35 × 61 ) / 1
LCM(99,35,61) = 211365 / 1
LCM(99,35,61) = 211365
Here are some samples of GCF of Fractions calculations.
