here the logic is
R1 = first digit * second digit
R2 = second digit * third digit
R3 = third digit * first digit
so final number is

R1R2R3(R1+R2+R3 – second digit)

for 532=1561028
R1 => 5*3 = 15
R2 = 3*2 = 6
R3 = 2*5 = 10

final number = 15610(15+6+10-3) => 1561028

same logic is true for new two numbers as well

by the same logic for 821
R1 = 8*2 = 16
R2 = 2*1 = 2
R3 = 1*8 = 8

final number 1628(16+2+8-2) => 162824
