a b means the greatest common divisor of a and b a b means t

(a, b) means the greatest common divisor of a and b [a, b] means the least common multiple of a and b List all of the positive divisors of434 and 589 Find (434, 589) Find [434, 589]

Solution

a.

Divisors fo 434:    1,2,7,14,31,62,217,434

Divisors of 589:     1,19,31,589

b.

[434,589]=31*2*7*19=8246

Only common divisors are:1 and 31

So greatest common divisor is: 31 =(434,589)

c. Least common multiple is:

 (a, b) means the greatest common divisor of a and b [a, b] means the least common multiple of a and b List all of the positive divisors of434 and 589 Find (434
