What is the largest prime factor of the number 7221?

To find the largest prime factor of 7221, we need to divide it by prime numbers starting from 2. By dividing, we find that 7221 can be written as 3 * 7 * 109. Since 109 is a prime number and the largest factor, it is indeed the largest prime factor of 7221.

Math question: What is the prime factorization of the number 7221?

To find the prime factorization of 7221, we begin by finding its prime factors. By performing trial division, we find that 7221 can be factored as follows: 7221 = 3 × 7 × 7 × 47. Therefore, the prime factorization of 7221 is 3 × 7² × 47. Prime factorization is a process of breaking down a number into a product of its prime factors. In this case, 7221 is divisible by 3, 7, and 47, with 7 occurring twice. Thus, the prime factorization represents the unique combination of primes that, when multiplied together, yield the original number.

Math question: What is the sum of the digits of the number 7221?

To find the sum of the digits, we need to add the individual values of each digit. For the number 7221, the sum would be calculated as follows: 7 + 2 + 2 + 1 = 12. Thus, the sum of the digits of 7221 is 12.
