The factors of 42 is: 1, 2, 3, 6, 7, 14, 21, and 42 .Since it has more factors in addition to ' 1 ' and 42, it's composite.All even numbers other than 2 are composite.1, 2, 3, 6, 7, 14, 21, 42All even numbers other than 2 are composite.1, 2, 3, 6, 7, 14, 21, 42
3 and 7?
'98' is a COMPOUND Number. Compound numbers are the product of the multiplication of two( or more) smaller numbers. 2 x 49 = 98 ( So '98' is a compound number) NB Any even number , except '2' , is a compound number. Even numbers are those that end in 0,2,4,6,8 NNB Prime numbers always, except '2' itself, end in an odd number, except '5'. So e.g. 1,000,002 is Compound, it ends in '2' . It is NOT prime. 1,000,000,015 is a compound number, because it ends in '5'. The odd number exception.
They are: 1 2 4 7 14 and 28 note that 2 and 7 are prime numbers

No. 7, itself, is a multiple of 7 [7 * 1 = 7] and it is not a composite.
1, 2, 3, 6, 7, 14, 21, 42

2 and 7 are both prime 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 are neither prime, nor composite. 227 is prime.
The factors of 42 is: 1, 2, 3, 6, 7, 14, 21, and 42 .Since it has more factors in addition to ' 1 ' and 42, it's composite.All even numbers other than 2 are composite.1, 2, 3, 6, 7, 14, 21, 42All even numbers other than 2 are composite.1, 2, 3, 6, 7, 14, 21, 42
The prime numbers between 1 and 10 are 2, 3, 5, and 7.1 is just 1 - it is not prime or composite.4, 6, 8, 9, and 10 are composite.2, 3, 5, 7
