Do the division, if there is no remainder, it is divisible. Seriously, many of the "divisibility rules" that have been discovered become more complicated than doing the actual division. For practical purposes, just learn the divisibility rules for a few simple cases (divisibility rules by 2, 4, 8, 5, 10, 3, 9, 7, 11, and 13), and for all other cases, just do the division.

1000 times 1000 is divisible by 2, 4, 5, 8 and 10.

Those for 1, 2, 4, 5 and 8.

3 and 9. And they divide into 123456789 whether or not you use divisibility rules!

It is divisible by any of its factors which are: 1, 2, 3, 6, 7, 14, 21 and 42

Divide by two and five. 1, 2, 4, 5, 10, 20

2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.

The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.

350 is a composite number. it can be divisible by 10, 35, 5, 2 etc. You will find it easier to tell between prime and composite if you know the divisibility rules. one simple one is that if a number ends with zero it is divisible by 10...there are a lot of other divisibility rules.

the divisibility rule for 2 is: The number is even;the last digit ends with a 2,4,6,8,10, etc.The divisibility rule fir 3 is: The sum of the number is divisible by 3The divisibility rule for 4 is: The last two digits are divisible by 4The divisibility rule for 5 is: The number ends with a 5 or 0The divisibility rule for 6 is: The sum CAN be divisible by 2 and or 3The divisibility rule for 9 is: The sum of the number is divisible by 9The divisibility rule for 10 is : The number ends with a 0
