1, 2, 4, 8 and 16.
the set of factors
1,2,3,5,6,10,15,30
All numbers have factors. The whole number factors of a composite number are the integers that combine in a multiplication sentence to make that number. In the sentence 5 x 6 = 30, 5 and 6 are factors of 30.
1,2,3,4,6,12
We know that 143 is a whole number and that it has to be either prime or composite because all whole numbers other than 0 and 1 are one or the other. So, in order to determine if it is prime or composite, we need to know if any numbers besides 1 and 143 are factors. 1, 11, 13, and 143 are factors so 143 is a composite number.
I'm pretty sure the answer would be 1,2,4,16 (:
It is a composite number because it has more than two factors.
13 and 19 aren't composite. 1,2,5,10 1,13 1,2,3,6,9,18 1,19
We can't answer this accurately if you don't tell us the groups to choose from.
90 has factors other than 1 and itself, so it is not a prime number. For example, 90 is 9 x 10, so it is a composite number.
When a composite number is expressed as a product of its prime factors, the prime factorization of the composite number has been performed.
Composite. All whole numbers ending in four are composite.
