Question

How many numbers between 6000 and 9000 are coprime to 9000

Answer 1

Hi there,

The question is answered following;

Find the LCM of 2, 3, 5 is 30.

Find at a set of 30 numbers and see how many you would find.

You will find 8 such numbers which are co-prime to 2, 3 and 5.

Every 30 numbers, you will find 8 numbers  

So, for 3000 numbers, you will find 800 numbers.

Hence for 9000 numbers you would find 2400 numbers.

I hope the question is answered.

Thanks for asking.
