Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 28/187,788/862
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 28,788
Greatest Common Factor of Numerators i.e. GCF of 28,788 is 4 .
LCM of Denominators means LCM of 187,862 as per the given fractions.
LCM of 187,862 is 161194 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 28,788
2 | 28, 788 |
2 | 14, 394 |
7, 197 |
∴ So the GCF of the given numbers is 2 x 2 = 4

1,2,4,197,394,788
Greatest Common Factor
We found the factors 28,788 . The biggest common factor number is the GCF number.
So the greatest common factor 28,788 is 4.
Lets's calculate LCM of 187,862
Given numbers has no common factors except 1. So, there LCM is their product i.e 161194
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/161194
Therefore, the GCF of Fractions 28/187,788/862 is 4/161194
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 187,862 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(187,862) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(187,862) x common factors =1 x 1 = 1
LCM(187,862) = ( 187 × 862 ) / 1
LCM(187,862) = 161194 / 1
LCM(187,862) = 161194
