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 smallest factor of any positive integer is 1.
It's always 1.
6
1 is.
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.
There is only one factor of 18 that's equal to 9.That factor is 9 .
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
You could be 33.
13
#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(); }
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
