Lets's calculate GCF of 973,830
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 973
:1,7,139,973
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 973,830 . The biggest common factor number is the GCF number.
So the greatest common factor 973,830 is 1.
Lets's calculate LCM of 31,637
Given numbers has no common factors except 1. So, there LCM is their product i.e 19747
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19747
Therefore, the GCF of Fractions 973/31,830/637 is 1/19747
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 31,637 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,637) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(31,637) x common factors =1 x 1 = 1
LCM(31,637) = ( 31 × 637 ) / 1
LCM(31,637) = 19747 / 1
LCM(31,637) = 19747
