QUESTION:

Problem 27E

What is the least common multiple of each pair in Exercise 25?

ANSWER:

Solution:-

Step1

Given that

We have to determine what is the “least common multiple” of the pair in Exercise 24?

Step2

a) 37 · 53 ·73, 211 · 35·59

Definition: -  The least common multiple of two integers c and d  are the smallest positive integer that is divisible by both c and d.

The positive common multiple of two number is

lcm     (lcm=least common multiple)

lcm

Therefore, the least common multiple of each pair of integers is .

Step3

b) 11 · 13· 17, 29 · 37 · 55 · 73

The positive common multiple of two number is

lcm
