Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 685/67,136/449
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 685,136
Greatest Common Factor of Numerators i.e. GCF of 685,136 is 1 .
LCM of Denominators means LCM of 67,449 as per the given fractions.
LCM of 67,449 is 30083 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 685,136
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 685
List of positive integer factors of 685 that divides 685 without a remainder.
1,5,137,685
Factors of 136
List of positive integer factors of 136 that divides 136 without a remainder.
1,2,4,8,17,34,68,136
Greatest Common Factor
We found the factors 685,136 . The biggest common factor number is the GCF number.
So the greatest common factor 685,136 is 1.
Lets's calculate LCM of 67,449
Given numbers has no common factors except 1. So, there LCM is their product i.e 30083
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30083
Therefore, the GCF of Fractions 685/67,136/449 is 1/30083
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 67,449 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,449) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,449) x common factors =1 x 1 = 1
LCM(67,449) = ( 67 × 449 ) / 1
LCM(67,449) = 30083 / 1
LCM(67,449) = 30083
