No. 9 is a multiple of 3, an equal or larger number which is the product of factors.
The product is negative.
Take your pick! Which one do you want it to be? 75: It is the only number that is the product of three (an odd number of) prime factors. 360: It is the only number with three different prime factors. 100: It is the only number that is the product of two pairs of two prime factors. 25: It is the only number that is a square of a prime. 51: It is the only semi-prime. 4000: It is the only number that is a product of 8 prime factors. So, given these unique characteristics, it is always possible to define a set in such a way that the stated characteristic makes that number the "odd one out".
If you mean 'prime' factors, then an odd number of them CAN'T produce a perfect square. Consider 3 factors ... A, B, and C. If their product were a perfect square, then AxB=C, which can't be true if C is a prime number. For non-prime factors, an odd number of them may or may not be a perfect square: Three factors = not a square: 2 x 3 x 5 = 30. Three factors = a square: 2 x 3 x 6 = 36.
30 is the first with three distinct prime factors.
12
2 x 2 x 3 x 3 = 36 4 x 3 x 3 = 36 4 x 9 = 36
two factors is a binomial three factors is a trinomial four of more is a polynomial the product of any of these is just a polynomial
The sign of the factors. These are the rules: * If there is a zero factor, the product is zero. * If there is an even number of negative factors (two, four, six, etc. odd factors), the product is positive. * If there is an odd number of negative factors (one, three, five, etc. odd factors), the productd is negative.
No. 9 is a multiple of 3, an equal or larger number which is the product of factors.
The product is negative.
If by "least number" you mean "smallest positive integer", then the answer is the product of the three smallest primes: 2x3x5 = 30
The way to be sure you have one of these is to take any three distinct prime numbers and multiply them. Those three prime numbers are then the only factors the product can have. An example is the number 30, which has factors of 2, 3 and 5.
3x - 3
This is called a factor. Factors, by definition, are numbers you can multiply together to get another number, or a product.
30 cannot be written as the product of 6 prime numbers. 30 has three prime factors: 2 x 3 x 5 = 30
The number 9: factors are 9, 3, and 1.
