Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 485/859,623/721
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 485,623
Greatest Common Factor of Numerators i.e. GCF of 485,623 is 1 .
LCM of Denominators means LCM of 859,721 as per the given fractions.
LCM of 859,721 is 619339 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 485,623
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 485
List of positive integer factors of 485 that divides 485 without a remainder.
1,5,97,485
Factors of 623
List of positive integer factors of 623 that divides 623 without a remainder.
1,7,89,623
Greatest Common Factor
We found the factors 485,623 . The biggest common factor number is the GCF number.
So the greatest common factor 485,623 is 1.
Lets's calculate LCM of 859,721
Given numbers has no common factors except 1. So, there LCM is their product i.e 619339
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/619339
Therefore, the GCF of Fractions 485/859,623/721 is 1/619339
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 859,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(859,721) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(859,721) x common factors =1 x 1 = 1
LCM(859,721) = ( 859 × 721 ) / 1
LCM(859,721) = 619339 / 1
LCM(859,721) = 619339
