The number is 1.
Any number divided by 1 equals itself. Therefore, if we want a number divided by 1 to equal 1, that number must be 1.
Here's a simple equation to illustrate:
x / 1 = 1
To solve for x, we multiply both sides of the equation by 1:
x = 1 * 1
x = 1
Therefore, the only number that satisfies the condition is 1.
