Yes.
They are both composite. Relatively composite isn't a thing.
6, 10, 15, 30 are the composite factors of 30.
15 and 30 are both composite numbers because each has more factors than 1 and the number itself.
1, 2, 3, 5, 6, 10, 15, 30, composite
30 is divisble by 1, 2, 3, 5, 6, 10, 15 and 30; these are all factors of 30. Out of these factors composite numbers are 6, 10, 15 and 30.
No!
30 and 15 are both composite numbers. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.
Yes, 30 is a composite number: its factors are 1, 2, 3, 5, 6, 10, 15 and 30.
The composite factors of 30 are the numbers that can be multiplied together to give the product of 30. These factors include 1, 2, 3, 5, 6, 10, 15, and 30. Composite factors are different from prime factors, which are numbers that can only be multiplied by 1 and themselves to give the original number.
1, 2, 3, 5, 6, 10, 15, 30
The gcf is 15; so 30 and 135 are not relatively prime. 30 = 2 x 3 x 5 135 = 33 x 5 hcf = 3 x 5 = 15 If the gcf of two numbers is 1, then they are relatively prime 15 ≠ 1, thus 30 and 135 are not relatively prime.
No. 15 is a common factor
