29 and 31 are prime.
The rest are composite numbers.
Prime numbers: 11, 13, 17, 19, 23, 29 Composite numbers: 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30
the first one 11 others are not 15 = 3 x 5 21 = 3 x 7 27 = 3 x 9 56 = 4 x 14
NO. Not all odd numbers are prime like 9, 15, 21, 27,... because they have other factors aside from 1 and itself.
23 and 27 are prime numbers whereas 36 and 39 are composite numbers.
13
No, neither of them are.
No.
They are all prime numbers except for 15 21 25 and 27 which are composite numbers
YES
If you mean: 12 13 15 17 27 and 29 then the prime numbers are 13 17 and 29
Prime numbers: 11, 13, 17, 19, 23, 29 Composite numbers: 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30
14 = 2 × 7 27 = 3³ → hcf(14, 27) = 1 → 14 and 27 are relatively prime.
the first one 11 others are not 15 = 3 x 5 21 = 3 x 7 27 = 3 x 9 56 = 4 x 14
No, neither 27 nor 57 are prime numbers.
NO. Not all odd numbers are prime like 9, 15, 21, 27,... because they have other factors aside from 1 and itself.
Neither 27 nor 52 are prime numbers. Both are composite numbers, instead.
To find the GCF of two numbers, you first need to express them as the product of their prime factors. For 14 and 27, this is: 14 = 2x7 27 = 3x3x3 The next step would be to identify any common factors. In this case, however, there are no common prime factors. Therefore, the GCF of 14 and 27 is 1.
