it always has at least 2 factors
I need to disagree on this one, since the number 1 only has one factor.
Can you guess, which factor it does have :-)
The sum of the factors of any negative number is zero.
69,440
2, 4, 6, 10, 12, 20, 30, 60 add up to 144.
To find the common factors of 9 and 18, we first need to list the factors of each number. The factors of 9 are 1, 3, and 9, while the factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 9 and 18 are 1, 3, and 9. Adding these common factors together gives us a sum of 13.
3, 12, 30
The smallest prime number that is a factor of the sum of 32009 and 52009 is: 2
The factors from greatest to least are: 11,11,5,3,3. The smallest prime factor is 3. You can get a quick idea of this by the fact that the digital root (number that goes evenly into the sum off all digits) is 18 which is divisible by 3.
1 and 16 are factors of 32 and their sum is 17 which is an odd number
991
#include<stdio.h> #include<conio.h> void factor(int num) { int i,sum=0; for(i=1;i<num;i++) { if(num%i==0) { sum=sum+i; } } printf("Sum of the factor of %d is %d",num,sum); } void main() { int num; printf("Enter the number="); scanf("%d",&num); factor(num); getch(); }
You could be 33.
13
65 has 13 as a factor because 13 divides into 65 evenly with no remainder. The sum of the digits of 65 is 11 because 6 + 5 = 11
Smallest even number 2Smallest odd number 12 + 1 = 3

samllest factors of 250 are 50 and 5 and the sum of 50 and 5 is 50+5=55
No - since the only factor of 83 apart from itself is 1, the sum of its factors is 1, not itself.
