The concept of prime factorisation is normally applied to positive integers only. This is because once you consider negative numbers, the results become ambiguous.
One of the most important theorems of factorisation is that the prime factorisation of any integer is unique. That does not apply to negative integers. As long as an odd number of factors is negative, the overall product is negative so,
-42 = -2*3*7 or 2*(-3)*7 or 2*3*(-7) : hardly unique!
What else can I help you with?
What is the least common multiple of 28 and 42 found using prime factorization?
First you need to find the prime factors of 28 and 42. 28= 7x22 42= 7x3x2 Then you multiply 7x3x22, the product of which is 84, which is your answer.
Prime factorization for 84?
The prime factor decomposition of 84 is: 2 x 2 x 3 x 7 If you want to see my working (in case I made a mistake): 84/2=42 (42 is not prime), 42/2=21 (21 is not prime), 21/3=7 (7 is prime, so stop here) factors: 2,2,3 and 7
The prime factorization of 42 using exponents?
'42' being an even number will divide by '2' Hence 2)42 = 21 3)21 = 7 7 ) 7 = 1 So the prime factors of '42' are 2^(1) X 3^(1) x 7^(1). #NB the '1' is the exponent. 2,3, & 7 are the primes.

The prime factors of 42 are 2, 3 and 7.
Is the prime factorization of 42 is 21 x 2?
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
Can you explain why the prime factorization of 42 is 21 2?
In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.
What is the prime factorization for -42?
The prime factors of 42 are 2, 3, and 7. These prime numbers multiplied create 42.2*3*7 = 422 x 3 x 7 = 42.

No.
What prime factorization is for 2 x3x7?
42
Is the prime factorization of 42 21 x 2?
Prime Factorization of 42No, 21 X 2 is not the prime factorization of 42 because 21 is a composite number.2 X 3 X 7 is the prime factorization of 42 because all the factors are prime numbers.To arrive at the prime factorization in this particular case, you had to factor 21 down to its prime factors, not forgetting that one of the prime factors of 42 was already 2.2 X 21 = 423 X 7 = 21, so the prime factorization of 42 is:2 X 3 X 7No, 21 is not prime. Try 2 x 3 x 7.
