Divisibility by 5

10 is divisible by 5. Every number with last digit 0 is also divisible by 5, because we can present it as sum of tens.

For example: 40 is divisible by 5 , because
40 = 10 + 10 + 10 + 10

Multi-digit number, which doest not have last digit 0, we can present as sum of number with last digit 0 and ones.

For example: 425 = 420 + 5
428 = 420 +8

425 is divisible by 5 because the two addends(420 and 5) are divisible by 5
428 is not divisible by 5 because one of the addends(8) is not divisible by 5

So, if a multiciphered number can be divided by 5 depends only on the digit of the ones; If this digit is 5 or 0, the number is divisible by 5

Numbers divisible by 5 are only those which have 0 or 5 for last digit

Divisibility by 5 examples:
Numbers 105,275,315,420,945,760 can be divided by 5
Numbers 151, 246, 879, 1404 can not be divided by 5
