Composite Numbers

150 and 169.

The number 1 and any other number having exactly two factors (1 and itself) is not a composite number.

To write a BASIC program that checks if an input number is prime or composite, you can use a loop to test divisibility. First, prompt the user for a number and then check if it's less than 2 (which is neither prime nor composite). For numbers greater than 1, iterate from 2 to the square root of the number, checking if it divides evenly (using the modulus operator). If you find a divisor, the number is composite; otherwise, it's prime. Here's a simple example:

INPUT "Enter a number: ", N
IF N < 2 THEN PRINT "Neither prime nor composite": END
IS_PRIME = TRUE
FOR I = 2 TO SQR(N)
    IF N MOD I = 0 THEN
        IS_PRIME = FALSE
        EXIT FOR
    END IF
NEXT I
IF IS_PRIME THEN PRINT N; " is prime" ELSE PRINT N; " is composite"

The composite numbers between 45 and 70 are 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, and 69. Composite numbers are those that have more than two positive divisors. These numbers can be divided evenly by numbers other than 1 and themselves.

A composite number is a positive integer that has at least one positive divisor other than one and itself. Between 15 and 30, the composite numbers are 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, and 30. For example, 18 is composite because it can be divided by 1, 2, 3, 6, 9, and 18.

Installing composite decking without a space between the boards is not recommended. Adequate spacing is necessary to allow for expansion and contraction due to temperature changes and moisture absorption. Without proper gaps, the boards can warp, buckle, or become damaged over time. It's essential to follow the manufacturer's guidelines for spacing to ensure the longevity and performance of the decking.

Not every multiple of 5 is a composite number. A composite number has more than two distinct positive divisors, while a prime number has exactly two. The number 5 itself is a multiple of 5 and is prime, as its only divisors are 1 and 5. Therefore, while many multiples of 5 are composite (like 10, 15, and 20), 5 itself serves as a counterexample.

1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169 and 196. Fourteen of them.

a composite means it has more multiples then itself and one 58 can be divided by 2 and equals 29 so it is composite because it has more the one set of factors

18 and 20

No, 43 is prime because it's only factors are itself and 1.

The factors of 76 are 1, 2, 4, 19, 38, and 76.

The composite factors are 4, 38, and 76.

It is 96 because it has more than two factors which makes it a composite number

397 is a prime number.

They are: 21 22 24 25 26 27 28 because 23 and 29 are prime numbers

Nine is composite. The factors of 9 are: 1 3 9

4 6 8 9 10 12 14 15 16 18 20 21 22 24 25 26 27 28 30 32 33 34 35 36 38 39 40 42 45 46 48 49 50.

The numbers 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39 and 40 are composite (including the boundaries).

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100

231517 is composite number. 19 is a prime number.

Answering for myself >:D

Found it out!

Divide it by the divisor (the denominator).

The answer depends on how the numbers are combined: addition, subtraction or multiplication.
