Question

2. Write the smallest and the largest 4-digit numbers and determine the prime factorisation of each​

Answer 1

Step-by-step explanation:

The greatest four digit number will be 9999.

Its prime factors are

\therefore 9999=3\times3\times11\times101.∴9999=3×3×11×101.

Solution:

The greatest four-digit number = 9999.

9999 is the greatest four-digit number, because if 1 can be added to the 9999 then the number becomes 5-digit i.e. 10,000.

Prime factorization of 9999 gives:

If the factors for any number that are identified as their prime numbers, then that factors are referred to be the Prime factors. The tree diagram which is used for finding the factors of the number is called as prime factorization method.
