The factors of 991 are 1, 991
The factors of 212 are 1, 2, 4, 53, 106, 212
The HCF of 991,212 is 1.
Lets's calculate GCF of 991,212
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 991
:1,991
Now, list down the factors of 212
:1,2,4,53,106,212
Greatest Common Factor
We found the factors 991,212 . The biggest common factor number is the GCF number.
So the greatest common factor 991,212 is 1.
Lets's calculate LCM of 31,907
Given numbers has no common factors except 1. So, there LCM is their product i.e 28117
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28117
Therefore, the GCF of Fractions 991/31,212/907 is 1/28117
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 31,907 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,907) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,907) x common factors =1 x 1 = 1
LCM(31,907) = ( 31 × 907 ) / 1
LCM(31,907) = 28117 / 1
LCM(31,907) = 28117
