Thread: Greatest Multiple

Let M (p,q,r,N) be the largest positive integer less than N or equal to N that has only p , q AND r as its distinct prime factors. ex 100(2,3,5)
output = 90 because 2*3^2*5.

Code:

#include <stdio.h>int main()
{
    int d = 100, num=1;
    while(num < 10){
        if(num*5 < d){
            num*=5;
        }
        else if(num*3<d){
            num*=3;
        }
        else if(num*2<d){
            num*=2;
        }
        }
    
    printf("%d", num);
    return 0;
}

My apologies Salem

Code:

#include <stdio.h>
#include <stdlib.h>
//John Raphael B. Pascua
int main(){
    int a = 3,b = 7,c = 11,d = 1000000, e = a*b*c;
    while(e < d){
     if(e * c < d){
         e *=c;
     }else if (e * b < d){
         e *=b;
     }else if (e * a < d){
         e *=a;
     }
    }
    printf(" %d\n", e);
    return 0;
}

nvm just did it right hahaha thanks for always replying to all my posts salem
