Problem: is the number 621 prime or composite? method: in the last lesson, we learned to find all. Problem: is the number 621 prime or composite? method: in the last lesson, we learned to find all factors of a whole number to determine if it is prime or composite. To determine if a number is prime or composite, follow these steps: find all factors of the number.

Thus we need a better method for determining if a large number is prime or composite. Thus, if we could find one factor of 621, other than 1 and itself, we could prove that 621 is composite. One way to find factors of large numbers quickly is to use tests for divisibility. Definition example one whole number is divisible by another if, after dividing, the remainder is zero. If one whole number is divisible by another number, then the second number is a factor of the first number.

A divisibility test is a rule for determining whether one whole number is divisible by another. Divisibility test for 3: if the sum of the digits of a number is divisible by 3, then the number is divisible by 3. We can test for divisibility by 3 see table above to quickly find a factor of 621 other than 1 and itself. Since the factors of 621 include 1, 3 and 621, we have proven that 621 has more than two factors. Divisibility tests example a number is divisible by 2 if the last digit is 0, 2, 4, 6 or 8. 168 is divisible by 3 since the sum of the digits is 15 1+6+8 15 , and 15 is divisible by 3.

A number is divisible by 4 if the number formed by the last two digits is divisible by 4. A number is divisible by 8 if the number formed by the last three digits is divisible by 8. 549 is divisible by 9 since the sum of the digits is 18 5+4+9 18 , and 18 is divisible by 9. Let 039 s look at some examples in which we test the divisibility of a single whole number. 150 is divisible by 3 since the sum of the digits is 6 1+5+0 6 , and 6 is divisible by 3. 150 is not divisible by 9 since the sum of the digits is 6, and 6 is not divisible by 9.
