Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 869/257,749/272
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 869,749
Greatest Common Factor of Numerators i.e. GCF of 869,749 is 1 .
LCM of Denominators means LCM of 257,272 as per the given fractions.
LCM of 257,272 is 69904 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 869,749
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 869
List of positive integer factors of 869 that divides 869 without a remainder.
1,11,79,869
Factors of 749
List of positive integer factors of 749 that divides 749 without a remainder.
1,7,107,749
Greatest Common Factor
We found the factors 869,749 . The biggest common factor number is the GCF number.
So the greatest common factor 869,749 is 1.
Lets's calculate LCM of 257,272
Given numbers has no common factors except 1. So, there LCM is their product i.e 69904
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/69904
Therefore, the GCF of Fractions 869/257,749/272 is 1/69904
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 257,272 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,272) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,272) x common factors =1 x 1 = 1
LCM(257,272) = ( 257 × 272 ) / 1
LCM(257,272) = 69904 / 1
LCM(257,272) = 69904
