36 has 8 positive, integral factors:1, 2, 3, 4, 9, 12, 18, 36=========================Addendum:The mathematical world was stunned today at the announcement that anotherpositive integral factor of 36 has been identified. Investigators at Lincoln #22elementary school in Rochester NY have proven that ' 6 ' is included in thatcategory. Textbooks will now need to be revised to reflect the true numberof factors of 36 as nine, instead of the eight that we were all taught. Journalistsare already referring ironically to the number ' 6 ' as the "Pluto factor".
The positive whole-number factors of 42 are: 1, 2, 3, 6, 7, 14, 21, and 42.
6

The number 175 is an odd number. This number, 175 has four positive factors (35,5 and 25,7). These number are all positive and when multiplies equal 175.
25
Three of them.
There are 44 positive integers less than 2,010 that have an odd number of factors.

It can have any number: from none upwards.
The number 853 is prime - it has no positive integer factors other than itself and 1.
To find the number of positive factors of 125, we start with its prime factorization: (125 = 5^3). To determine the number of positive factors, we take the exponent of each prime factor, add 1, and then multiply the results. Thus, the number of positive factors is (3 + 1 = 4). Therefore, 125 has 4 positive factors: 1, 5, 25, and 125.
Two. 101 is a prime number; its only factors are 1 and itself.
