(ex. 3412, 3512, 4312, 4512, 5312, 5412)

Step-by-step explanation:

Without repetition there would be 24 numbers divisible by 4 using these digits. There are six combinations for each ending of 12, 24, 32 and 52 (ex. 3412, 3512, 4312, 4512, 5312, 5412) so 4 x 6 = 24 combinations. If you can repeat digits there are are many more combinations.
