Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 84/847,97/689
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 84,97
Greatest Common Factor of Numerators i.e. GCF of 84,97 is 1 .
LCM of Denominators means LCM of 847,689 as per the given fractions.
LCM of 847,689 is 583583 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 84,97
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 84
List of positive integer factors of 84 that divides 84 without a remainder.
1,2,3,4,6,7,12,14,21,28,42,84
Factors of 97
List of positive integer factors of 97 that divides 97 without a remainder.
1,97
Greatest Common Factor
We found the factors 84,97 . The biggest common factor number is the GCF number.
So the greatest common factor 84,97 is 1.
Lets's calculate LCM of 847,689
Given numbers has no common factors except 1. So, there LCM is their product i.e 583583
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/583583
Therefore, the GCF of Fractions 84/847,97/689 is 1/583583
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 847,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(847,689) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(847,689) x common factors =1 x 1 = 1
LCM(847,689) = ( 847 × 689 ) / 1
LCM(847,689) = 583583 / 1
LCM(847,689) = 583583
