Math Question: What is the smallest prime number that can evenly divide 1554?

To find the smallest prime number that can evenly divide 1554, we start by checking if 2 is a divisor. Since 1554 is an even number, it does indeed divide evenly by 2. The result is 1554 ÷ 2 = 777. Next, we check if 3 is a divisor. Adding up the digits of 1554 gives 1 + 5 + 5 + 4 = 15, which is divisible by 3, so 3 is a divisor as well. Dividing 1554 by 3 gives 1554 ÷ 3 = 518. Finally, we check if 5 is a divisor, but it is not. Therefore, the smallest prime number that evenly divides 1554 is 2.

Math question: What is the square root of the greatest perfect square less than 1554?

To find the square root of the greatest perfect square under 1554, we need to identify the perfect square closest to 1554. By taking the square root of 1554, we get approximately 39.44. Therefore, the greatest perfect square less than 1554 is 1521 (39^2). So, the square root of 1521 is 39.

What is the cube root of 1554? How many 3-digit numbers can be formed using the digits of 1554? How many different ways can 1554 be expressed as the sum of two distinct prime numbers? How many numbers less than 1554 are divisible by both 6 and 9?
