Complete the analogy 14 : 70 :: 23 : ? after working out how the second number of the first pair is formed.

Add the digits of the number and multiply the number by that total: 1 + 4 = 5 and $14\times 5=70$. For 23 the digit total is 2 + 3 = 5, so $23\times 5=115$. The trap 69 is $23\times 3$, using only the last digit; 46 is $23\times 2$, using only the first digit; and 125 is $5\times 5\times 5$, cubing the digit total instead of multiplying the number by it.
