The factor pairs of 16 are (16,1)(8,2)(4,4)
If put in order then the last factor of a number is the number itself. So, 50 is the last factor of 50.
If the number can be divided by 4 exactly then 4 is a factor. No matter how long the number is, if the last two digits of the number are divisible by 4, then 4 is a factor of the number. Conversely, if the last two digits are not divisible by 4, then 4 is not a factor.
5 is not a factor of 9347. 5 is a factor of a number only if the last digit of the number is a 0 or a 5.
Even.
If the last two digits of your target number are a multiple of 4, 4 is a factor of the whole number.
last number should be a prime number
the factors are the first and the the last number.
12
no because the last number of 457 is seven and 7 does not devide equaliy into 3. so it is not a factor of 457
If the last number in the question is 0.000001, then yes, the conversion factor is 0.000001 or 10-6

Double the last digit, subtract it from the rest. If the result is divisible by 7, the whole number is divisible by 7.
