The sum is 195.
72 is an abundant number because the sum of its positive divisors, not including 72 itself, is larger than 72. Positive divisors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. 1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 18 + 24 + 36 = 123 > 72 (if an integer is larger than the sum of its positive divisors , not including the integer itself, then that integer is called a deficient number, such as prime or power of prime numbers or numbers like 10 are).

The sum of the positive whole-number factors of 30 is 72.
Here are the factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72 Some people leave 1 and/or the number itself out when totaling. I'll leave that up to you.
To find how many ways 72 can be set up in rows equally, we need to determine the divisors of 72. The divisors of 72 are the numbers that can evenly divide 72, which are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. In total, there are 12 divisors, meaning there are 12 different ways to set up 72 in rows equally.
The number that divides 72 can refer to any of its divisors. The divisors of 72 include 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72 itself. Each of these numbers can divide 72 without leaving a remainder.
The numbers that go into both 45 and 72 are their common divisors. The common divisors of 45 are 1, 3, 5, 9, 15, and 45, while the common divisors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The only common divisors between the two numbers are 1, 3, and 9. Thus, the numbers that go into both 45 and 72 are 1, 3, and 9.
62 + 72 = 85
The positive divisors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30. Thus d(30) = number of such divisors=8, ľ(30) = sum of such divisors=72 and ľ2(30) = sum of squares of such divisors= 1 + 4 + 9 + 25 + 100 + 225 + 900 = 1300. From the formula, since 30=2.3.5, we have d(30 = (1 + 1)(1 + 1)(1 + 1) = 8; ľ(30 = 22 ˇ1 2ˇ1 : 32 ˇ1 3ˇ1 : 52 ˇ1 5ˇ1 = 3 1 : 8 2 : 24 4 = 72 and ľ2(30) = 24 ˇ1 22 ˇ1 : 34 ˇ1 32 ˇ1 : 54 ˇ1 52 ˇ1 = 15 3 : 80 8 : 624 24 = 5:10:26 = 1300.

The number 72 is special for several reasons. Mathematically, it is a highly composite number, meaning it has more divisors than any smaller positive integer, totaling 12 divisors. Additionally, it appears in various cultural contexts, such as being the number of names of God in Kabbalistic tradition and the number of years in a traditional Jewish life cycle. In geometry, 72 degrees is significant as it relates to the angles in a regular pentagon.
