The HCF of 28,77,131 is 1.
Lets's calculate GCF of 28,77,131
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 28
:1,2,4,7,14,28
Now, list down the factors of 77
:1,7,11,77
Now, list down the factors of 131
:1,131
Greatest Common Factor
We found the factors 28,77,131 . The biggest common factor number is the GCF number.
So the greatest common factor 28,77,131 is 1.
Lets's calculate LCM of 27,25,44
Given numbers has no common factors except 1. So, there LCM is their product i.e 29700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/29700
Therefore, the GCF of Fractions 28/27,77/25,131/44 is 1/29700
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 27,25,44 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,25,44) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(27,25,44) x common factors =1 x 1 = 1
LCM(27,25,44) = ( 27 × 25 × 44 ) / 1
LCM(27,25,44) = 29700 / 1
LCM(27,25,44) = 29700
