Large numbers are numbers that are significantly larger than those ordinarily used in everyday life, for instance in simple counting or in monetary transactions. The term typically refers to large positive integers, or more generally, large positive real numbers, but it may also be used in other contexts.
Very large numbers often occur in fields such as mathematics, cosmology, cryptography, and statistical mechanics. Sometimes people refer to numbers as being "astronomically large". However, it is easy to mathematically define numbers that are much larger even than those used in astronomy.
Scientific notation was created to handle the wide range of values that occur in scientific study. 1.0 × 109, for example, means one billion, a 1 followed by nine zeros: 1 000 000 000, and 1.0 × 10−9 means one billionth, or 0.000 000 001. Writing 109 instead of nine zeros saves readers the effort and hazard of counting a long series of zeros to see how large the number is.

Method for finding factors of any number, large or small.
Math tutorial by Mr. Nate Mullins. Also prime factorization, using divisibility rules and number theory concepts to find factors of 43,368.
Write a function to add two very large numbers that cannot be stored in int.( out of range of int). For example String num1="1111.....1" (41 digits) and String num2= "33333....3" (41 digits). Then sum should be String sum = "44444....4"(41 digits) This channel is an ultimate guide to prepare for job interviews for software engineers, software test engineers, computer scientists, engineering students specially computer science and IT engineers, Master of computer application (MCA) and Bachelor of Computer Application (BCA) students.
