What is the GCF of 12,28,36?

1 answer:

5 0

To find the GCF, you have to list all factors of each number and find the first common one.

12 = 1, 2, 3, 4, 6, 12

28 = 1, 2, 4, 7, 14, 28

36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

the GCF of numbers 12, 28, 36 is 4.

hope this helps, God bless!

$B(\stackrel{x_1}{8}~,~\stackrel{y_1}{0})\qquad C(\stackrel{x_2}{9}~,~\stackrel{y_2}{-8}) ~\hfill BC=\sqrt{[ 9- 8]^2 + [ -8- 0]^2} \\\\\\ BC=\sqrt{1^2+(-8)^2}\implies \boxed{BC=\sqrt{65}}$
