3168/4752 = 0.6666666 = 2/3.

(so back to Primary 3 maths... 3168/2 = 1584. So now 4752/1584 = 3. Bingo, it's 2/3)

4r = 4/6 = 0.666666 = 2/3

In other words, your base factor/dimensions/aspect ratio is 2/3 so just send and develop.
That mean i don need to crop also i will get a 4R photo izzit ?? Cos my max pixel is 3168 : 4752 = 4 : 6 = 2 : 3 all are = to 0.666666666666666. In other ward if i wanted to change the perspective of my photo, i still can crop to a 4R size photo rite ??? because my actual pixel size is big enough for me to crop it to a smaller size pixel but still i will get a 4R size photo if i crop to a ratio of 4:6 or 2:3 ??

yup, can.

a decent 4R print out only need 1200 pixel by 1800 pixel. (300 pexel per inch)

So can i said that the minimum size i can crop down is until 1200 pixel by 1800 pixel ?

You may see some upsampling artefacts, like if you zoom into an image 150% in an image viewer.
