Without knowing what the product is, it will be difficult to help. Presumably, you can tell the difference between even and odd numbers. If you are trying to predict, the product of two evens is even, the product of two odds is odd and the product of an even and an odd is even.
What else can I help you with?
What two numbers LCM that is the product of the numbers?
Any two that are relatively prime.
What two number pairs whose least common factor is the product of the number?
Any pair of prime or relatively prime numbers.
What is a product of a prime factor?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
What numbers have the greatest common factors of one?
Co-prime numbers, relatively prime numbers and any set of prime numbers.
Is the LCM of a prime number and a composite number a multiple of the prime number?
Yes, the least common multiple (LCM) of a prime number and a composite number will always be a multiple of the prime number. This is because the LCM is the smallest number that is a multiple of both numbers. Since the prime number is a factor of itself and the LCM is a multiple of both numbers, the LCM will always be a multiple of the prime number.
Are there any pairs of prime numbers that when multiplied do not make their least common multiple?
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
Is it true that the product of any two prime numbers are always odd?
Not always because as for example 2*19 = 38
When is the product of two prime numbers not a prime number?
The product of any two numbers, neither of which is 1, is never a prime number.
Is the product of any two odd number always prime?
NO. The product of any two prime numbers are not always odd.Examples:2 x 3 = 62 x 5 = 102 x 11 = 22
Is the product of any two prime numbers is always odd?
No, because 2 is prime. Otherwise the product of two odds is odd, and all primes are odd except 2.
Why are the multiples of any number other than one not prime numbers?
The multiples of any number cannot be prime numbers because such numbers are the product of at least two numbers. Prime numbers, but definition, cannot be cannot be the product of any numbers except itself and one.
Why is the least common multiple of 2 prime numbers their product?
Because prime numbers don't have any common prime factors. Their GCF is 1. Since the product of the GCF and LCM of a pair of numbers equals the product of the numbers, the LCM has to be equal to the product.
What is the LCM of any two prime numbers?
Their product.
Why do you think the least common multiple is not always the product of the two numbers?
The prime factorization of the LCM will contain all the prime factors of the two original numbers. When the original numbers don't have any prime factors in common, (the GCF is 1) the LCM will be their product. When the two original numbers have prime factors in common (the GCF is 2 or more) the duplicates will be discarded and the LCM will be less than their product.
Can any two prime numbers be relatively prime?
It is, and always is relatively prime.
What two numbers LCM that is the product of the numbers?
Any two that are relatively prime.
When two different prime numbers are multiplied can the product be a negative integer?
Since prime numbers are defined as positive integers, any product of prime numbers will be positive.
