# PIN code

PIN on Michael credit card is a four-digit number. Michael told this to his friend:

• It is a prime number - that is, a number greater than 1, which is only divisible by number one and by itself.

• The first digit is larger than the second.

• The second digit is greater than the third.

• The third digit is greater than 6.

• The fourth digit is even.

• Three digits are odd.
