The proper factors of a number are all the factors less than itself, so the proper factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, and 63. In some cases, the number 1 is excluded from the list of proper factors, too.
Actually, no! 126 is an even number because it factors up with 2.
126
2, 3 and 7
The proper factors of a number do not include one and the number itself.
"Proper factors" are all of a number's factors except one and the number itself.
the proper factors are the factors of a number not including the number itself, or 1.
The proper factors are the regular factors without one and the number itself.
Any multiple of 126.
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.
The set of factors includes one and the number itself. Proper factors do not include those two.
No, no prime number has proper factors.
One has no proper factors.
