The factors of 7 are 1, 7
The factors of 12 are 1, 2, 3, 4, 6, 12
The factors of 31 are 1, 31
The HCF of 7,12,31 is 1.
Lets's calculate GCF of 7,12,31
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 7
:1,7
Now, list down the factors of 12
:1,2,3,4,6,12
Now, list down the factors of 31
:1,31
Greatest Common Factor
We found the factors 7,12,31 . The biggest common factor number is the GCF number.
So the greatest common factor 7,12,31 is 1.
Lets's calculate LCM of 973,978,997
Given numbers has no common factors except 1. So, there LCM is their product i.e 948739218
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/948739218
Therefore, the GCF of Fractions 7/973,12/978,31/997 is 1/948739218
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 973,978,997 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(973,978,997) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(973,978,997) x common factors =1 x 1 = 1
LCM(973,978,997) = ( 973 × 978 × 997 ) / 1
LCM(973,978,997) = 948739218 / 1
LCM(973,978,997) = 948739218
