WebIf n is perfectly divisible by i then, i will be the factor of n. In each iteration, the value of i is updated (increased by 1). This process goes until test condition i <= n becomes false,i.e., this program checks whether number entered by user n is perfectly divisible by all numbers from 1 to n and all displays factors of that number. WebJan 25, 2015 · We know that $$ 12 = 2^2\cdot 3^1. $$ Now observe the following expression: $$ ({2}^{0} + {2}^{1} + {2}^{2}) \cdot ({3}^{0} + {3}^{1}). $$ As you can see, each of the terms achieved after expanding is a divisor of $12$. And hence the formula for the number of divisors $= (3)(2) = (2 + 1)(1 + 1) = 6$. You can try this for any number. how much robux is chroma gemstone worth

WebWell, every whole number is divisible by 1. This is a whole number, so 1 is a factor at the low end. 1 is a factor. That's its actual smallest factor, and its largest factor is 120. You can't have something larger than 120 dividing evenly into 120. 121 will not go into 120. So the largest factor on our factors list is going to be 120.

"WebDivisors of an integer in Python. We will first take user input (say N) of the number we want to find divisors. Then we will run a loop from 1 to (N+1). We do so because if we run the loop from 0 (zero) then we will get ‘Division By Zero Error’. And if we run it only N times then we will not get the number (N) as its own divisor.
