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.

It is divisible by any of its factors which are: 1, 2, 3, 6, 7, 14, 21 and 42
What are the divisibility rules of all prime numbers?
The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.
Which of the Divisibility Rules go on 741?
The rule for 1 and the rule for 3.
How can divisibility rules help you to find the prime factorization of 53?
The divisibility rules will show that 53 is not divisible by anything other than 1 and itself. Since it is already prime, it doesn't have a factorization.

It is divisible by any of its factors which are: 1, 3, 31 and 93
What are the divisibility rules from 1-25?
26
How do you know when you fount all the factor pairs of 26?
You only have to test the numbers 1 through 5. If you know the rules of divisibility, you know that 3, 4 and 5 aren't factors.
What are the divisibility rules of factor 855?
1 3 9 19 57 95 171 285 855
What divisibility rules can be used to find the factor pairs of 80?
Those for 1, 2, 4, 5 and 8.
What does it means to use the divisibility rules to find factor pairs for eighty?
Factors are divisors. If you know the divisibility rules, you know that 80 is divisible by 1, 2, 4, 5 and 8. If you divide 80 by those numbers, you find the other half of the factor pairs.
What are the divisibility rules of 42?
It is divisible by any of its factors which are: 1, 2, 3, 6, 7, 14, 21 and 42
What are the divisibility rules from 1-20?
21
What divisibility rules are 141divisible by?
I am not sure what you are asking but 141 is divisible by the number 1, itself (141) and certainly by the number 3 so it is not a prime number.
