The least 4 factors of 144 are 1, 2, 3, and 4 .
There is no divisibility rule for 13 because it is a prime number. If you are thinking: why is there a divsibility rule for 2 and 3 then. Well, i don't know so go look it up on google.
Just carry out the division.
It is 3 6 9
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
By tautology. If it did not work, it would not be a divisibility rule!
A number is a multiple of 4 if the last 2 digits are a multiple of 4 The 10s digit is even and the last digit is 0, 4 or 8 The 10s digit is odd and the last digit is 2 or 6 A number is a multiple of 8 if the last 3 digits are a multiple of 8 The 100s digit is even and the last 2 digits are a multiple of 8 The 100s digit is odd and the last 2 digits are 4 times an odd number
1, 2, 4 and 47
1, 2, 3 and 4
What is the divisblity rule by 8
There is no easy rule for divisibility by 34.
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
Able to Be Divided
A number is a multiple of 36 if it's a multiple of 4 and 9 at the same time For example 108 is a multiple of 36 because it ends in 08, which means it's a multiple of 4, and 1 + 8 = 9, which means it's a multiple of 9

Judging by some of the questions asked on this site, the first rule is that divisibility is a concept that applies only to whole numbers.
