∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Now, list down the factors of 3451
:1,7,17,29,119,203,493,3451
Greatest Common Factor
We found the factors 830,3451 . The biggest common factor number is the GCF number.
So the greatest common factor 830,3451 is 1.
Lets's calculate LCM of 685,849
Given numbers has no common factors except 1. So, there LCM is their product i.e 581565
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/581565
Therefore, the GCF of Fractions 830/685,3451/849 is 1/581565
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 685,849 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(685,849) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(685,849) x common factors =1 x 1 = 1
LCM(685,849) = ( 685 × 849 ) / 1
LCM(685,849) = 581565 / 1
LCM(685,849) = 581565
