cwrw238 · Answer

first look at the numbers  and find their greatest common factor  (GCF)

cwrw238 · Answer

they are all even so 2 is a possibility
write them as prime factors

18 = 2*3*3

cwrw238 · Answer

will  6 or 9 divide exactly into 184?

yanasidlinskiy · Answer

hang on....

yanasidlinskiy · Answer

no

cwrw238 · Answer

ok  so the GCF of the numbers is 2

the GCF of the variables is easy 
eg  q^3, q^2 and q  
the greatest factor which divides into these 3 is q

the terms in r are all r^2  so GCF of these is  r^2

so your GCF  is 2qr^2

take this out and divide each term by 2qr^2 to getthe  other factor in the parentheses
