No.
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.
No.
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
It is: 2*3*7 = 42
To find the least common multiple (LCM) of 34 and 42, we first need to find the prime factorization of each number. The prime factorization of 34 is 2 x 17, and the prime factorization of 42 is 2 x 3 x 7. The LCM is the product of the highest power of each prime factor that appears in either factorization, so the LCM of 34 and 42 is 2 x 3 x 7 x 17, which equals 714.
42
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
42 = 2 × 3 × 7
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.
The prime factors of 42 are 2, 3 and 7.
