Because both of them just misread the multiplicand and the multipliers are not misread, we should first find out the multipliers, that is, the greatest common divisor of 255 and 365 (by short division).

And then decompose 255 and 365.

255=5 1*5

365=73*5

The pony misread the number in the single digit of the multiplicand instead of the ten digit, so the ten digit of the original number is 5.

Tiger misread the number in the tenth place of the multiplicand, not the single digit, so the single digit of the original number is 3.

So the original multiplicand is 53.

53*5=265
