The answer is 454585.

Just multiply the first no. with the second and the third numbers, and then add the two products and minus from them the second number ;This is a example: 5 + 3 + 2 = 151022
1) 5 x 3 = 15 {the first 2 digits} 2) 5 x 2 = 10 {the second two digits} 3) (15 + 10) - 3 = 22 {the third two digits}
