28 = 22 × 7
42 = 2 × 3 × 7
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
They are: 37+5 = 42
The prime factors of 42 are 2, 3 and 7.
The least common multiple (LCM) of 28 and 42 can be found by determining the prime factorization of both numbers. The prime factorization of 28 is (2^2 \times 7) and for 42, it is (2 \times 3 \times 7). The LCM is found by taking the highest power of each prime: (2^2 \times 3^1 \times 7^1 = 84). Therefore, the LCM of 28 and 42 is 84.
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.
42
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!
30 and 42
28 = 2 * 2 * 7 = 22 * 742 = 2 * 3 * 7
42 and 48
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.
The prime factorization of 42 ia: 2 x 21 2 x 3 x 7. The prime prime factors of 42 are 2, 3, 7.
