# Is 430 is a Composite number

## Is 430 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 430 is composite or not first we have to find its factors.

### Factors of 430:

• If we have taken numbers from 1, 2, 3…for checking factors of 430, we found that 430 has factors 1, 2, 5, 10, 43, 86, 215 and 430. Hence, we must say that 430 is a composite number.
• Thus, 430 is the composite umber.
• If we multiply 430 by 1, 2, 3 then we get the multiples of 430 which are 430, 860 and so on.

• 430 has more than two factors which are 1, 2, 5, 10, 43, 86, 215 and 430 and hence it is the composite number.
• 430 is the even composite number and it is not the perfect square also.
• If we divide 430 by 1, 2, 5, 10, 43, 86, 215 and 430 then we get remainder as zero. Hence, 1, 2, 5, 10, 43, 86, 215 and 430 are the factors of 430.

### Note:

• 430 is not the perfect square.
• Factors of 430: 1, 2, 5, 10, 43, 86, 215 and 430
• Prime factors of 430: 2, 5, 43

### Conclusion:

• 430 is the composite number which has factors 1, 2, 5, 10, 43, 86, 215
• And hence, 430 is not the prime number.
