Alexxandr [17]

Answer:

The number 9,99,973 is not prime number as 13, 61 and 97 are factors of 999973 apart from 1 and the number itself.

Step-by-step explanation:

We have to check whether 999973 is a prime number or not.

Prime factorization is a method where we break a number into product of prime numbers.

We first prime factorize the given number:

999973 = 13\times 13\times 61\times 97

Prime Number:

  • A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller numbers.
  • A natural number greater than 1 that is not prime is called a composite number.
  • Thus, a prime number cannot have factor other than 1 and the number itself.

Thus, we can say that the number 9,99,973 is not prime number as 13, 61 and 97 are factors of 999973 apart from 1 and the number itself.
