40+60= 100
40×60= 2400
2400/100= 24
40 and 60 are the pair number
If the product of the two numbers is the sum times 24, then the product of the two numbers is 2400. 40 times 60 is 2400, and 40 plus 60 is 100. The two numbers are 40 and 60.
There are infinitely many solutions for that. Choose ANY number as the first number. The subtract 100 minus this number, to get the second number.
38 + 62 = 100 38 x 62 = 2,356
24 of them.
0.27 x 100 = 27
A single number cannot have a product. A product is a sum involving two or more numbers.
You can not use the number 1, 2, 3, 4 to get a product 100. This is because 100 also has 5 as its factor. So you cannot get the product 100 without using 5.

There are 9 integers less than 100 that have an odd number of factors.Every factor of a number has a pair, eg 2 & 3 are a factor pair of 6; and so it would be expected that every number has an even number of factors.However, if the factor pair of a number are the same number (eg 6 & 6 are a factor pair of 36), then there will be an odd number of factors.When there is a repeated factor like this, the number is a perfect square.Thus only perfect squares have an odd number of factors.Less than 100 there are 9 perfect squares (1, 4, 9, 16, 25, 36, 49, 64 & 81) which have an odd number of factors.100 itself is a perfect square and also has an odd number of factors, but the question asked for those numbers less than 100 with an odd number of factors.
The smallest prime number is 2 and the greatest prime number less than 100 is 97. The required product is: 2 x 97 = 194.
