Re: I need help
And you can tell that since 5 and 29 are prime.
You may recall that every integer can be represented by a product of prime numbers. Also, this product is unique. Thus, once you find this product, the only other divisors are multiples of these or 1 and the number itself.
Since 5 * 29 is your number, multiples of these can not divide 145.
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
