The proper factors of 14 are 1, 2, and 7.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The proper factors are 1, 2, 3, 6, 7, 14, and 21or 2, 3, 6, 7, 14, and 21 if the number 1 is excluded as it is in some definitions of proper factor.
2, 3, 6, 7, 14, 21
Proper factors do not include one and the number itself.
Prime numbers don't have proper factors.
The proper factors of 14 are 1, 2, and 7.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The proper factors are 1, 2, 3, 6, 7, 14, and 21or 2, 3, 6, 7, 14, and 21 if the number 1 is excluded as it is in some definitions of proper factor.
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.
