This transfer is possible in two ways: direct transfer and using the decimal system.
first, let\'s make a direct transfer.
let\'s do a direct translation from hexadecimal to binary like this:
170CDF_{16} = 1 7 0 C D F = 1_{(=0001)} 7_{(=0111)} 0_{(=0000)} C_{(=1100)} D_{(=1101)} F_{(=1111)} = 101110000110011011111_{2}
answer: 170CDF_{16} = 101110000110011011111_{2}
now let\'s make the transfer using the decimal system.
let\'s translate to decimal like this:
1∙16^{5}+7∙16^{4}+0∙16^{3}+12∙16^{2}+13∙16^{1}+15∙16^{0} = 1∙1048576+7∙65536+0∙4096+12∙256+13∙16+15∙1 = 1048576+458752+0+3072+208+15 = 1510623_{10}
got It: 170CDF_{16} =1510623_{10}
Translate the number 1510623_{10} в binary like this:
the Integer part of the number is divided by the base of the new number system:
1510623  2                     
1510622  755311  2                    
1  755310  377655  2                   
 1  377654  188827  2                  
  1  188826  94413  2                 
   1  94412  47206  2                
    1  47206  23603  2               
     0  23602  11801  2              
      1  11800  5900  2             
       1  5900  2950  2            
        0  2950  1475  2           
         0  1474  737  2          
          1  736  368  2         
           1  368  184  2        
            0  184  92  2       
             0  92  46  2      
              0  46  23  2     
               0  22  11  2    
                1  10  5  2   
                 1  4  2  2  
                  1  2  1  
                   0   

the result of the conversion was:
1510623_{10} = 101110000110011011111_{2}
answer: 170CDF_{16} = 101110000110011011111_{2}
