They are: 2, 3 and 7
126 is a composite number
First, you have to find the number that is a multiple of 7. That number is 126 because 7 x 18 = 126. Then, you need to find the prime factorization. You can do that by starting with any factor pair of 126 and keep factoring the composite factors until all factors are prime. 126: 2 x 61 Since 2 and 61 are prime, that is the prime factorization of 126.
If you mean the product of its prime factors then it is: 2*3*3*7 = 126
That's not a prime factorization because 9 isn't prime, but it does represent the number 126.
The answer is 2, its an even number.
2 x 3 x 3 x 7 = 126
2, 3 and 7
125
The HCF is 9
29 is a prime number, its as simple as it gets 29/126 is as low as you can go
317 is a prime number
1 and 7 both do
