Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 90/39,54/47,936/62
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 90,54,936
Greatest Common Factor of Numerators i.e. GCF of 90,54,936 is 18 .
LCM of Denominators means LCM of 39,47,62 as per the given fractions.
LCM of 39,47,62 is 113646 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 90,54,936
2 | 90, 54, 936 |
3 | 45, 27, 468 |
3 | 15, 9, 156 |
5, 3, 52 |
∴ So the GCF of the given numbers is 2 x 3 x 3 = 18

Greatest Common Factor
We found the factors 90,54,936 . The biggest common factor number is the GCF number.
So the greatest common factor 90,54,936 is 18.
Lets's calculate LCM of 39,47,62
Given numbers has no common factors except 1. So, there LCM is their product i.e 113646
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 18/113646
Therefore, the GCF of Fractions 90/39,54/47,936/62 is 18/113646
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 39,47,62 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,47,62) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,47,62) x common factors =1 x 1 = 1
LCM(39,47,62) = ( 39 × 47 × 62 ) / 1
LCM(39,47,62) = 113646 / 1
LCM(39,47,62) = 113646
