17 points! asap!

i need an example of two numbers that do *not* have a gcf (greatest common factor).

For example like 10 and 3 they dont really have one they both have a gcf of 1

Lets say  your GCF is 20 the ones that would NOT apply are

3,6,7,8,9,11,12,13,14,15,16,17,18,19 because those number can NOT equal up to 20 within a multiple

and these are the ones that do apply 1,2,4,5,10,20  because 1*20=20 2*10=20 4*5=20 5*4=20 10*2=20 20*1=20

Hope this helps if you need a better explanation let me know

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
