Greatest Common Factor
We found the factors 823,409 . The biggest common factor number is the GCF number.
So the greatest common factor 823,409 is 1.
Lets's calculate LCM of 670,471
Given numbers has no common factors except 1. So, there LCM is their product i.e 315570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/315570
Therefore, the GCF of Fractions 823/670,409/471 is 1/315570
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 670,471 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(670,471) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(670,471) x common factors =1 x 1 = 1
LCM(670,471) = ( 670 × 471 ) / 1
LCM(670,471) = 315570 / 1
LCM(670,471) = 315570
