Search a string of at least five numbers (for example, 65403) Identify all of the substrings that form numbers that are divisible by 3.

I guess a hint is that to see if a number is divisible by 3, you can add up the digits of the number and if the sum is divisible by 3, the number is divisible by 3. Another way of seeing if a number is divisible by 3 is to do an integer divide and then multiply back to see if you get what you started with. For example, 7 / 3 = 2. 2 * 3 = 6, thus 7 is not divisible by 3.

As for all the substrings, start at the 5th number and do substrings of length 1 to 5, Move to the next digit, do substrings of length 1 to 4. Move to the next digit, do substrings of length 1 to 3. Repeat until only 1 digit is left.

Good luck,

Paul

Draw a flowchart that accepts two number and checks if the first is divisible by the second

I think the big question here is how do you determine in the first number is divisible by the second number. With a calculator, try various combinations of number to see when the first number is divisible by the second number and when it is not divisible. How are the results different from when they are divisible from when they are not divisible?

Good luck,

Paul

Why are 21,25,27, etc not prime numbers?

A prime number is a number that's evenly divisible only by one and itself. 21 is divisible by 3 and 7, 25 is divisible by 5, and 27 is divisible by 3.

Is 450 divisible by 3 in fractions

450=9*5*10=9*50
9*50/3=3*50=150
To verify if a number is divisible by 3, add the digits in the number. If the sum of digits is divisible by 3, then thumber is also divisible by 3.
Sum of digits in 450 =4+5+0 =9, divisible by 3, so 450 is also divisible by 3.

How do i factor numbers on a ti-30xs calculator

This calculator does not have a key that you can use to find the prime factor of an integer.
You can however use the calculator to find the factors
1. If number is even divide it by 2
Keep dividing by 2, while keeping track of how many times you divided by 2.
If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5
2. Now try dividing by 3, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.
If you divided 4 times by 3, your second factor is 3^4
3. Divide by 5, until you can't any more. Keep track of the number of times you divided by 5.
4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

Example: 23100
Division by 2
23100/2=11550 ---------> 1 division by 2
11550/2=5775 ----------> 2 divisions by 2
Note that 5775 is not divisible by 2. No more divisions by 2.
First factor is 2^2

Division by 3:
5775/3=1925 ----------> 1 division by 3
1925/3=641. 66667 Not an integer. No more divisions by 3.
2nd factor is 3^1

Division by 5 (number ends in 5)
1925/5 =385 -------> 1 division by 5
385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)
3rd factor is 5^2

Division by 7
77/7=11 --------> 1 division by 7, and no more
4th factor is 7^1=7

Division by 11
11/11=1
5th factor is 11^1=11

Assembling the factors 2^2, 3^1, 5^2, 7, 11
Prime factorization of 23100 is
23100=(2^2)(3)(5^2)(7)11
