Question

Q. Find the least positive integer which on adding 1 is exactly divisible by 126 and 600. (please do it fast... Tomorrow is my exam..)

Answer 1

Answer:

find the L.C.M of 126 and 600 which is 12600

so, n+1=12600

= 12600-1

=12599

Answer 2

Answer:

12599

To find:

Find the least positive integer which on adding 1 is exactly divisible by 126 and 600.

Solution:

The given numbers are 126 and 600

let the least positive integer be 'n'

Then the least positive integer which on adding 1 is exactly divisible by 126 and 600 will be 'n + 1'

LCM of 126 and 600 is 12600

so n + 1 = 12600

n = 12600 - 1 = 12599

Conclusion:

The least positive integer which on adding 1 is exactly divisible by 126 and 600 is 12599.
