👉 In mathematics, a "viraginous number" is one that is divisible by both 2 and 9. This means that it can be expressed as a product of two numbers, where each of those numbers is also a divisor of 9. For example, 36 (which is divisible by 2) is also a viraginous number because it can be written as the product of 2 and 18: \[ 36 = 2 \times 18
