They are the numbers that have more than two factors in them.
150 and 169.
6, 10, 15, 25, 30, 50, 75, 150
152, 153, 154
No, because it is divisible by other numbers than 1 and 150 alone.
138, 140, 141, 142, 143, 144, 145, 146, 147, 148, 150 (including 138 and 150)
all the compounds in the world are either 50 70 115 150
For any integer greater than 5, where the units digit is 5 then that number can be expressed as the product of n and 5. As such, the number is composite. Therefore all numbers in the range 150 to 200 that have a units digit of 5 are composite,.
Not all composite numbers are even, but all even numbers except 2 are composite.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
composite numbers are those that have more than 2 factors. all even numbers other than 2 are composite numbers and some odd numbers are composite numbers. numbers that are prime are the numbers that are not composite numbers i hope this answers your question :)
Both are composite numbers
