Editing Divisibility rule (section)

===Divisibility by 6===
Divisibility by 6 is determined by checking the original number to see if it is both an even number ([[#Divisibility by 2|divisible by 2]]) and [[#Divisibility by 3 or 9|divisible by 3]].<ref name="product-of-coprimes"/> 

If the final digit is even the number is divisible by two, and thus may be divisible by 6. If it is divisible by 2 continue by adding the digits of the original number and checking if that sum is a multiple of 3. Any number which is both a multiple of 2 and of 3 is a multiple of 6.

'''Example.'''
# 324 (The original number)
# Final digit 4 is even, so 324 is divisible by 2, and may be divisible by 6.
# 3 + 2 + 4 = 9 which is a multiple of 3. Therefore the original number is divisible by both 2 and 3 and is divisible by 6.
