the number one.
3.14 has a finite number of digits. All numbers with a finite number of digits are rational. Pi has an infinite number of digits, AND the digits don't repeat in a regular pattern. (Numbers with repeating decimals are rational as well.)
A number with more than 2 digits must be at least 100. Any two numbers of this kind will give an answer that is at least 10000. So there are no ways to make 144 with multiplication of numbers with more than 2 digits.
The final product
All numbers which are not "zero" are classed as significant digits. Therefore in the number 129 there will be three digits which are classed as significant.
555
Try the different numbers - there are only 11 after all - and multiply their digits. Or analyze the factors of the number 21.

All numbers are made with digits and there is no limit on how big they can be. So there is no greatest number.

Multiply the number by all of the numbers from 1 to infinity.
A number with more than 2 digits must be at least 100. Any two numbers of this kind will give an answer that is at least 10000. So there are no ways to make 144 with multiplication of numbers with more than 2 digits.
The final product
All numbers which are not "zero" are classed as significant digits. Therefore in the number 129 there will be three digits which are classed as significant.
All three numbers are significant digits, so 3.
The answer is Zero (0) because that is what you get when you multiply by zero, and zero is one of the numbers on the telephone keypad.
