Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 670/89,611/781
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 670,611
Greatest Common Factor of Numerators i.e. GCF of 670,611 is 1 .
LCM of Denominators means LCM of 89,781 as per the given fractions.
LCM of 89,781 is 69509 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 670,611
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 670
List of positive integer factors of 670 that divides 670 without a remainder.
1,2,5,10,67,134,335,670
Factors of 611
List of positive integer factors of 611 that divides 611 without a remainder.
1,13,47,611
Greatest Common Factor
We found the factors 670,611 . The biggest common factor number is the GCF number.
So the greatest common factor 670,611 is 1.
Lets's calculate LCM of 89,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 69509
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/69509
Therefore, the GCF of Fractions 670/89,611/781 is 1/69509
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 89,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(89,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(89,781) x common factors =1 x 1 = 1
LCM(89,781) = ( 89 × 781 ) / 1
LCM(89,781) = 69509 / 1
LCM(89,781) = 69509
