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
42 21.2 7,3,2 7,3,2 21,2 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!
Find the prime factorization. It doesn't matter if you use a factor tree, or rainbow or firework. For example: 42 42 21,2 3,7,2 The prime factorization of 42 is 2 x 3 x 7. The greatest prime factor is 7.
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.
42 = 42 / / 6 7 = 2 x 3 x 7 / / 2 3
No, 21 is not prime.
No.
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
Take 30/42, for example. The prime factorization of the numerator (30) is 2 x 3 x 5. The prime factorization of the denominator (42) is 2 x 3 x 7. This will help you find the GCF or the LCM.
It is: 2*3*7 = 42
