Zero. 5 is a prime so its only factors are 1 and 5. It, therefore, has no proper factors.
2 + 5 + 10 + 25 = 42
5 is a prime number so it doesn't have proper factors
1, 5, 7, and 35 are the factors of 35. The proper factors are 5 and 7.
The odd factors of 70 are: 1, 5, 7, and 35. The sum of these factors is 48.
The odd positive integer factors of 70 are: 1 5 7 35 The sum of these factors is 1 + 5 + 7 + 35 = 48
1, 3, 5, 9, 15, 45 (sum = 78).
Factors of 20 are 1, 2, 4, 5, 10 and 20. And their sum is 1 + 2 + 4 + 5 + 10 + 20 = 32.
To find the common factors of 25 and 80, we first determine the factors of each number. The factors of 25 are 1, 5, and 25, while the factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors shared by both numbers are 1 and 5. To find the sum of these common factors, we add them together: 1 + 5 = 6. Therefore, the sum of all the common factors of 25 and 80 is 6.
1 + 5 + 13 + 65 = 84
1 + 15 + 3 + 5 = 24
samllest factors of 250 are 50 and 5 and the sum of 50 and 5 is 50+5=55
1 + 3 + 5 + 15 = 24
