C :

#include<stdio.h>

int fun(int n){
	int r=1,i;
	for(i=1;i<=n;i++){
		r=r*i;
	}
	return r;
}

void main(){
	int g,s,b,i,x1,x2,x3;
	for(i=100;i<=999;i++){
		g=i%10;
		s=i/10%10;
		b=i/100;
		x1=fun(g);
		x2=fun(s);
		x3=fun(b);
		if(i==x1+x2+x3){
			printf("%d",i);
		}
	}
}

C++ :

#include<iostream>
using namespace std;
int fac(int n){
	int r=1;
	for(int i=1;i<=n;i++){
		r=r*i;
	}
	return r;
}

int main(){
	int a,b,c;
	int m;
	for(int i=100;i<=999;i++){
			a=i/100;
			b=i%100/10;
			c=i%10;			
		if(i==fac(a)+fac(b)+fac(c)){
			m=i;	
			break;
		}		
	}
	cout<<m<<endl;
	return 0;
}

Pascal :

begin
write('145');
end.

Java :

public class Main {
	public static void main(String[] args) {
		int a = 0;
		int b = 0;
		int c = 0;
		
		
		for(int i = 100; i < 1000; i++) {
			a = i / 100;	
			b = i / 10 % 10;
			c = i % 10;
			int sum1 = 1;
			int sum2 = 1;
			int sum3 = 1;
			
			for(int k = 1; k <= a; k++) {
				sum1 *= k;
			}
			
			for(int j = 1; j <= b; j++) {
				sum2 *= j;
			}
			for(int t = 1; t <= c; t++) {
				sum3 *= t;
			}
			
			if(i == sum1 + sum2 + sum3) {
				System.out.println(i);
			}
			
		}
	}
}

Python :

import math

for n in range(100,1000):
    a=n//100
    b=n//10%10
    c=n%10
    if n==math.factorial(a)+math.factorial(b)+math.factorial(c):
        print(n)
    n+=1
