Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 120/42,122/827
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 120,122
Greatest Common Factor of Numerators i.e. GCF of 120,122 is 2 .
LCM of Denominators means LCM of 42,827 as per the given fractions.
LCM of 42,827 is 34734 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 120,122
2 | 120, 122 |
60, 61 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 120
List of positive integer factors of 120 that divides 120 without a remainder.
1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120
Factors of 122
List of positive integer factors of 122 that divides 122 without a remainder.
1,2,61,122
Greatest Common Factor
We found the factors 120,122 . The biggest common factor number is the GCF number.
So the greatest common factor 120,122 is 2.
Lets's calculate LCM of 42,827
Given numbers has no common factors except 1. So, there LCM is their product i.e 34734
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/34734
Therefore, the GCF of Fractions 120/42,122/827 is 2/34734
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 42,827 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,827) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(42,827) x common factors =1 x 1 = 1
LCM(42,827) = ( 42 × 827 ) / 1
LCM(42,827) = 34734 / 1
LCM(42,827) = 34734
