## Is 2978 is a composite number or not ?

• As we already know that, the number having factors 1 and the number itself is the prime number.
• And numbers having more than these two factors are the composite numbers.
• To check whether the number 2978 is composite or not first we have to find its factors.

### Factors of 2978:

• If we have taken numbers from 1, 2, 3…for checking factors of 2978, we found that 2978 has factors 1, 2, 1489 and 2978. Hence, we must say that 2978 is a composite number.
• Thus, 2978 is the composite number.
• If we multiply 2978 by 1, 2, 3 then we get the multiples of 2978 which are 2978, 5956 and so on.

• 2978 has more than two factors which are 1, 2, 1489 and 2978 and hence it is the composite number.
• 2978 is the even composite number and it is not the perfect square also.
• If we divide 2978 by, 1, 2, 1489 and 2978 then we get remainder as zero. Hence, 1, 2, 1489 and 2978 are the factors of 2978.
