So there is a rule about multiples of 9 in general: something is a multiple of 9 if and only if its digits add up to a multiple of 9. 6+4 = 10, so it is not a multiple of 9. There's also a neat trick to remembering the multiples of 9 below 99 with your fingers, but you can look this up if you're interested.

What is the divisibility rule for 64?
The divisibility rule for 64 states that a number is divisible by 64 if the last six digits of that number form a number that is divisible by 64. This is because 64 is (2^6), and thus, any number divisible by 64 must also be divisible by (2^6). In practical terms, you can check the last six digits of a large number to determine its divisibility by 64. If those digits form a number that can be evenly divided by 64, then the original number is also divisible by 64.
