Question

Find the least number that must be added to 129311 to make it perfect square​

Answer 1

Answer:

factorise it... on factorising the smallest number I got is 2639

$7 \: \: \: \: |129311 \\ 7 \: \: \: \: |18473 \\ 7 \: \: \: \: |2639 \\ 377 |377 \\ 1 \: \: \: \: \: | 1$

here we got 7 and 377 so 7*377 = 2639
