Hi Cbarker1,
It's just 4 multiplied by an integer. We might as well ignore the word 'integral' since it is redundant.

"An integer multiple of 4" or, as I Like Serena suggested, simply "a multiple of 4" is 4n where n is any integer. The positive "integer multiples of 4" are 4, 8, 12, 16, 20, etc. The negative "integer multiples of 4" are -4, -8, -12, -16, -20, etc. Although it is neither positive nor negative, we can consider 0 an "integer multiple of 4". It is 0= 4(0) and 0 is an integer.
