Want this question answered?
2.5 is not a factor. 5 is prime.
a composite factor is 2 3 5 7 and11. theres more but thats what i got
no 5 is not a composite number 10 15 20 and 25 are composite
The greatest common factor of a prime number & a composite number is 1 if the composite number is not divisible by the prime number. 81(composite number) is not divisible by 29(prime number) so, gcf(29,81) = 1.
No. Any number where 5 is a factor will end in 5 or 0
yes, 5 is a factor
composite(I can already see a factor of 3 and 5)
Composite, because it has more than just one factor. Any number (except 5) that ends in 5 is composite.
3 and 5
2 AND 5
The composite number 330 has those prime factors.
-- It ends in a 5, so 5 is a factor of it. -- The sum of its digits (15) is divisible by 3, so 3 is a factor of it. It probably has tons of other factors, but either of these is enough to prove that it's composite.
115 is a composite number. This means it can be divided by other numbers besides 1 and itself. 115 can be divided by 1, 5, 23, and itself.115 is a composite number. It ends with 5 and is divisible by 5.
155 five is composite. It is composite because it has 5 as a factor. The only number that can be neither prime nor composite is 1.
1, 2, 5, 10 10 is the only composite factor.
How about 4 because 1 is not a prime or a composite number
95 is a composite number. Its factors are 1, 5, 19, and 95, of which 95 is the only composite factor. The prime factors of 95 are 5 x 19.
