Find the highest common factor (H.C.F) OF 168 and 252.
blondinia [14]
Let's first write all the factors of 168 and 252.

168 - <span>1,2,3,4,6,7,8,12,14,21,24,28,42,56,84,168</span>
252 - 1,2,3,4,6,7,9,12,14,18,21,28,36,42,63,84,126,252

84 is the GCF because 84 is greatest common factor of 168 and 252.

So, 84 is the GCF  

Hope this helps..  :)

3x+7= x-1 does x = -4?
vaieri [72.5K]
Subtract x from both sides:
(3x - x) + 7 = (x - x) - 1

3x - x = 2x:
2x + 7 = (x - x) - 1

x - x = 0:
2x + 7 = -1

Subtract 7 from both sides:
2x + (7 - 7) = -7 - 1

7 - 7 = 0:
2x = -7 - 1

-7 - 1 = -8:
2x = -8

Divide both sides by 2:
2x / 2 = -8 / 2

2 / 2 = 1:
x = -8 / 2

The gcd (greatest common denominator) of 8 and 2 is 2:
-8 / 2 = 2(-4) / 2x1 = 2/2 x - 4 = -4

x = -4
