What are the first four numbers which are equal to the product of all their factors?
Euclid proved that 2p−1(2p−1) is an even perfect number whenever 2p−1 is prime.
For example, the first four perfect numbers are generated by the formula 2p−1(2p−1), with p a Prime number, as follows: for p = 2: 21(22−1) = 6for p = 3: 22(23−1) = 28for p = 5: 24(25−1) = 496for p = 7: 26(27−1) = 8128.
All very true, but the question isn't about perfect numbers. The first four numbers that would satisfy the question's requirements are 1, 2, 3 and 5. If you feel 1 shouldn't be included, it would be 2, 3, 5 and 7 because only prime numbers are equal to the product of their factors.

What 2 consecutive odd numbers when added together equal the product of the 1st and 4th prime number?
The product of the first and fourth prime numbers (2 x 7) is 14. No two consecutive odd numbers add up to 14.
Why does the product of 4 negative numbers equal a positive?
If you know that the product of 2 negative numbers is positive, then the product of 4 negative numbers has to be positive. The product of the first two negative numbers is positive and the next two negative numbers is positive. Multiplying the product of the first two numbers (positive number) and the product of the last two numbers (also positive), is a positive number times a positive number which is positive. Let a, b, c and d be negative numbers: (a*b*c*d) = (a*b)*(c*d) (-ve*-ve*-ve*-ve)=(-ve*-ve)*(-ve*-ve)= (+ve)*(+ve) = (+ve)
Two consecutive negative integers have a product of 240 what are the integers?
First, we are not interested for the sign of the numbers, because the product of two negative numbers is always positive, so we need to find the two consecutive factors of 240, which are 15 and 16. Thus, the numbers are -16 and -15.
What is the product of the first two prime numbers which are bigger than forty?
A prime number is a number that's only factors are the number itself and one. So, the first two prime numbers after forty are forty-one and forty-three. Forty-one multiplied by forty-three is equal to one thousand, seven hundred, sixty-three.
Why does the product of 3 negative numbers equal a negative number number?
Because two negative multiplied together equal a positive. So after the first multiplication we have a positive and a negative. When we multiply these we have a negative.
What is the product of the first three even numbers?
The first three even numbers are 2, 4, and 6. To find the product of these numbers, you simply multiply them together: 2 x 4 x 6 = 48. Therefore, the product of the first three even numbers is 48.
