Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 84/90,62/83,93/821
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 84,62,93
Greatest Common Factor of Numerators i.e. GCF of 84,62,93 is 1 .
LCM of Denominators means LCM of 90,83,821 as per the given fractions.
LCM of 90,83,821 is 6132870 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 84,62,93
∴ 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 62
List of positive integer factors of 62 that divides 62 without a remainder.
1,2,31,62
Factors of 93
List of positive integer factors of 93 that divides 93 without a remainder.
1,3,31,93
Greatest Common Factor
We found the factors 84,62,93 . The biggest common factor number is the GCF number.
So the greatest common factor 84,62,93 is 1.
Lets's calculate LCM of 90,83,821
Given numbers has no common factors except 1. So, there LCM is their product i.e 6132870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6132870
Therefore, the GCF of Fractions 84/90,62/83,93/821 is 1/6132870
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 90,83,821 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,83,821) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(90,83,821) x common factors =1 x 1 = 1
LCM(90,83,821) = ( 90 × 83 × 821 ) / 1
LCM(90,83,821) = 6132870 / 1
LCM(90,83,821) = 6132870
