Answer:
1066528471
Step-by-step explanation:
[tex]\frac{6,666,666*666,666}{1+2+3+4+5+6+5+4+3+2+1}[/tex] - [tex]\frac{777,777*777,777}{1+2+3+4+5+6+5+4+3+2+1}[/tex]
The lowest common multiple is 1+2+3+4+5+6+5+4+3+2+1, so that;
= [tex]\frac{(6,666,666*666,666)-(777,777*777,777)}{1+2+3+4+5+6+5+4+3+2+1}[/tex]
= [tex]\frac{(444443955600)-(60493706170}{1+2+3+4+5+6+5+4+3+2+1}[/tex]
= [tex]\frac{38395024940}{36}[/tex]
= 1066528471
The solution to the given question is 1066528471.
