Solution

For this case we can do the following:

A) 15, 21

LCM= 105

15= 3*5

21 = 7*3

LCM= 3*5*7

b) 15,30

LCM= 30

15= 3*5

30 = 2*5

LCM= 2*3*5= 30

c) 24,72

LCM= 72

24= 2*3*4

72= 2* 2*2*3*3

LCM= 2*2*2*3*3

d) 16,42

LCM= 336

16= 2*2*4

42= 2*3*7

LCM= 2*2*3*7*4

e) 8,30

LCM=120

8= 2*4

30= 2*3*5

LCM= 2*3*4*5=120

f) 18,30

LCM=90

18= 2*3*3

90= 2*5*3*3

LCM= 2*5*3*3

g) 8,16,20

LCM= 80

8= 2*2*2

16= 2*2*2*2

20= 2*2*5

LCM= 2*2*2*2*5

7. Can you identify a goal as short-term or long-term?
vladimir2022 [97]

Answer:

Either one! If it is a long-term goal, it is to most likely have an effect on you for most of your life example: buying a house, going to college, etc.

A short term goal is something you could reach in just a few months and it will probably not have the same effect as the long term ones are, however some do. Example: changing your diet, eat healthier, etc.
