Math question: What is the largest prime factor of the number 1780?

To find the answer, we start by prime factorizing the given number. First, we divide it by 2 repeatedly until we get an odd number: 1780 ÷ 2 = 890. Still an even number, so we continue: 890 ÷ 2 = 445, which is odd. Then, we divide by 3: 445 ÷ 3 = 148. Next, we try 5: 148 ÷ 2 = 74, an even number. Continuing, we have 74 ÷ 2 = 37, which is finally odd. Now, we check if 37 is prime. It is indeed a prime number! Therefore, the largest prime factor of 1780 is 37. Finding prime factors helps us understand the fundamental building blocks of a number. In this case, 37 represents the largest prime factor, meaning it is one of the prime numbers that, multiplied together, yield the original number. By breaking it down, we gain insights into the number's divisibility, prime nature, and connections to other numbers. Furthermore, prime factorization enables efficient calculations involving factors, divisors, and multiples, playing a crucial role in various mathematical fields and applications.

Math question: If the number 1780 is multiplied by 4 and then divided by the sum of 20, what is the result?

To find the result, we multiply 1780 by 4, resulting in 7120. Next, we sum 20 to that number, obtaining 7140. Finally, we divide 7140 by 20, since that is the sum we used earlier. The final result is 357.

Math Question: If the number 1780 is divided by 22 and then multiplied by 5, what is the result?

To find the result, we start by dividing 1780 by 22, which gives us 81.36. Then, multiplying this result by 5 yields 406.8. Therefore, the result of dividing 1780 by 22 and then multiplying by 5 is approximately 406.8.
