Finding the Smallest Square Number Divisible by 4, 9, and 10


Step 1: Find the Prime Factors


To find the smallest square number divisible by 4, 9, and 10, we need to first find the prime factors of each number:

- 4 = 2 x 2
- 9 = 3 x 3
- 10 = 2 x 5

Step 2: Identify the Common Factors


Next, we need to identify the common factors among the prime factors:

- 2 x 2
- 3 x 3
- 2 x 5

Step 3: Multiply the Common Factors


To find the smallest square number that is divisible by all three numbers, we need to multiply the common factors:

2 x 2 x 3 x 3 x 2 x 5 = 180

Step 4: Find the Smallest Square Number


The smallest square number that is divisible by all three numbers is the square of the product of the common factors:

(2 x 2 x 3 x 3 x 2 x 5)^2 = 32400

Therefore, the smallest square number that is divisible by 4, 9, and 10 is 32400.
