8 + 16 + 40 + 48 + 72 + 80 + 120 + 144 + 240 + 360 + 720 = 1848
25% of 18000 = 18000*25/100 = 4500
No, it is not... For any number to be divisible by 9, the sum of its digits must ALSO divide by 9. In this case, 8+9+4+4=25... 25 is not divisible by 9 !
Factors of 25: 1, 5, 25 Their sum = 31 Difference between 31 and 8 = 23.
To determine the divisibility of 79810, we can check for divisibility by common factors. It is even, so it is divisible by 2. The sum of the digits (7 + 9 + 8 + 1 + 0 = 25) is not divisible by 3, so 79810 is not divisible by 3. Additionally, it ends in 0, which means it is divisible by 10. Thus, 79810 is divisible by 2 and 10.
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.

The number 975 is divisible by several integers, including 1, 3, 5, 15, 25, 39, 65, 195, 975, and others. It is also divisible by 5, as it ends in a 5, and by 3, since the sum of its digits (9 + 7 + 5 = 21) is divisible by 3. Additionally, 975 can be factored into its prime factors: 3, 5, and 13.
The odd factors of 32 are the factors that are divisible by 1 and 32, but are not divisible by 2. In this case, the odd factors of 32 are 1 and 32, as they are the only factors of 32 that are not divisible by 2. Factors such as 4, 8, and 16 are not considered odd factors because they are divisible by 2.
