As the question is phrased, the answer is 1/120 which would give the product 1: a perfect square. But the "correct" answer is, presumably, 30.
in order to get the result in mm or cm
No. If you have an odd number (for example 5) and an even number (say 2) and you multiply them together, you will get an even number (10). Therefore, just because the product of two numbers are even does not make both the numbers being multiplied together even (although at least one must be).
It is: 8 because 8*217800 = 1742400 which is a square number
5720*5 = 3600SQRT(3600) = 60
At least two zeros at the end.
At least two zeros at the end.
504 of course !
99, I would say.
There is no such thing as the product of just one number, a product is when 2 or more numbers are multiplied. The product of a number and another number means the answer you get when you multiply the two.
At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or irrational.

Yes it is possible to determine if a product will be even or odd. To do this, we need to consider what an even number is. Even numbers are numbers with at least one factor of 2 (meaning they are divisible by 2). Thus, any product of numbers which contains at least one even number will result in an even product. If all of the numbers being multiplied together are odd, the product will be odd. If one or more of the numbers is even, the product will be even.
Assuming the second even number is equal to 4 or greater, than the highest common factor of the two numbers is equal to an even number 2 or greater. Why can't an odd factor be used? Any odd factor must be multiplied by (at least) 2 to create an even product (ie. the 1st even number). That same odd factor must be multiplied by (at least 2) and any other number to create a 2nd even product, thereby making the Greatest Common Factor (at least) 2 times the odd number....which is an even number.
The least (or smallest) multiple is not a term typically used in mathematics. The least multiple of a number would be that number multiplied by 1. In other words, it would be the number itself.
