Question

HCF of two consecutive integers x and x+1 is_____

Answer 1

Let n be this number. We know it divides both x and x+1.
Let's look closer at x+1: we know that it divides x, so it also must divide 1. (Do you see why?) And 1 is divisble by what numbers?

Answer 2

by -1? rit?

Answer 3

When we're talking about factors, we usually restrict ourselves only to positive numbers. So not -1, but just 1.

Answer 4

oh thanx a lot

Answer 5

No problem.

Answer 6

but if it divides x how can it divide 1 also?
