What is a divisibility rule for 5?
If the rules for 2 and 3 work, the number is divisibale by 5.
Can you tell if whether 432 is divisible by 2 3 4 5 6 9 10?
Yes, you can tell using the divisibility rules. The answers are yes for all but 5 and 10.
What divisibility rules were combined to make the divisibility rule of 36?
You have to use the rules of 4 and 9 Using the rules of 2 and 18 won't work because the smallest common multiple of 2 and 18 is 18 not 36. 3 and 12 won't work either because the smallest common multiple of 3 and 12 is 12 not 36. However 4 and 9 does work because their biggest common divisor is 1 so multiplying them works. The biggest common divisor of 2 and 18 is 2 and the biggest common divisor of 3 and 12 is 3

It is divisible by 3 and 9 but not the others.
What are the divisibility rules for two and three?
If the number is even, it is divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3.
What are the divisibility rules that work for 93?
Being Divisibel by 3 and 31
How divisibility rules can help you find common factors?
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
