Sum of divisors = 91.
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 divisors of 36 are:{1, 2, 3, 4, 6, 9, 12, 18, 36}.36 is a square, thus there is an odd number of divisors (9, 7 proper). 6 * 6 (62) = 36 is the general one.
36
The greatest integer that will divide evenly into 36 is 36. 18 is 36's greatest proper factor.
100,000 has 36 divisors.
98 of them.
Nine divisors: 1, 2, 3, 4, 6, 9, 12, 18, 36.
the answer is 144, it is divisible by 1, 4, 9, 16, 36, and 144.
Sum of divisors = 91.
It is 1296.
Any of its factors
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).
1,815
It is 192.
25 is.
Composite, for it has four positive integer divisors, 1, 3, 9, 27. To be a prime number, it needs to have only two integer divisors, 1 and itself.
