right so now just divide all the numbers by 8
@chlobohoe it would have been great if you let the asker find it so that they can learn :)
OpenStudy (kidrah69):
List the prime factors of each number.
OpenStudy (anonymous):
lol sorry let me rephrase that. ITS 8 BECAUSE its the number that is a factor of each variable
OpenStudy (kidrah69):
You can do that with all of the numbers in the equation and you would know that the factor is 8 :) do you get it ? :)
OpenStudy (anonymous):
