You find the prime factorization of 42 like this.
You think what 2 number multiplied together give you 42:
6x7 7 is prime because the only factors it has is 1 and itself. 6 can be broken into 3x2.
So you currently have 7x3x2. All these numbers are prime so you just found the prime factorization!

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.
Is 87 prime factorization of 42?
No.
What is the LCM of 42 126 using prime factorization?
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
Is prim factorization of 42 is 21 times 2?
No, prime factorization of 42 is not 21 x 2 because 21 is not a prime number and it can be further broken into primes as 3 x 7. So prime factorization of 42 is 2 x 3 x 7.
What is the prime factorization of the composite number 42?
42=2x21 21=3x7 PF=2x3x7 The PF (Prime Factorization) of 42 is 2x3x7.(Sorry, I couldn't do a factor tree, there are always helpful to use when doing prime factorization, but since this is the computer, I could only do it like the following above.)
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

Are the prime factorization of 42 21x2?
No, 21 is not prime.
Is 87 prime factorization of 42?
No.
Is 21x 2 the only prime factorization of 42?
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
The prime factorization of 42?
It is: 2*3*7 = 42
Is 42 equals 212 a prime factorization?
No.
What prime factorization is for 2 x3x7?
42
What is the LCM of 42 126 using prime factorization?
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
Is a prime factorization of 42 is it 21x2?
42 = 2 × 3 × 7
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.
What is a prime factorization of -42?
The prime factors of 42 are 2, 3 and 7.
