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!
No exponents are needed because: 2 times 3 times 7 = 42
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.
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
6m = 42 Divide both sides by 6: m = 7
126 is a composite number; it has factors other than 1 and itself.The 12 factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126.The factor pairs of 126 are 1 x 126, 2 x 63, 3 x 42, 6 x 21, 7 x 18, and 9 x 14.The proper factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, and 63 or,if the definition you are using excludes 1, they are 2, 3, 6, 7, 9, 14, 18, 21, 42, and 63.The prime factors of 126 are 2, 3, 3, and 7. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The distinct prime factors of 126 are 2, 3, and 7.The prime factorization of 126 is 2 x 3 x 3 x 7 or, in exponential form, 2 x 32 x 7.-ProMode- Thank you :)1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126.
The prime factors of 42 are 2, 3 and 7.
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
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.
No, 21 is not prime.
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.
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
It is: 2*3*7 = 42
No.
42
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
42 = 2 × 3 × 7
