in the range 1 to 100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1 to 100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1 to 100 is prime or composite. ...
Prime numbers are those with only two elements, namely 1, and the digit itself. Think about the number 5, which really only contains two factors: 1 and 5. This indicates that the integer is prime. List the number 6, for example, which has far more that two factors, namely 1, 2, 3...

There are many puzzles in mathematics that can be solved more easily when we "break up" the Composite Numbers into their Prime Number factors.And a lot of internet security is based on mathematics using prime numbers in a subject called cryptography....
Name: ___ Prime and Composite Factors are the numbers you multiply to get another number. Prime numbers are the numbers that have only two factors. What are the factors of 3? 1 and 3 Because 3 has only two factors, it is a prime number. Composite numbers are the numbers that have...
70 = 1 x 70, 2 x 35, 5 x 14, and 7 x 10. Factors of 70: 1, 2, 5, 7, 10, 14, 35, 70. Therefore, Prime factorization: 70 = 2 x 5 x 7. Share with friends Previous Prime and Composite Numbers Next Divisibility Tests ...
Solution:Factors of 53 are 1 and 53. The number 53 is divided by only two numbers that are 1 and itself. Hence, 53 is a prime number. 2. Is 6 a prime number or composite number? Solution:Factors of 6 are 1,2,3, and 6. ...
