See this thread.Hi, I've got a problem here. I've tried using LCM and HCF, but it isn't working for me.
There are 3 positive whole numbers. Person 1 found the HCF of two of them, and got 1,000,004. Person's 2 + 3 did the same thing with different sets of those 3 numbers and got 1,000,006 and 1,000,008 respectively. Their teacher is sure one of them has made a mistake despite the fact they calculated the HCF of different numbers. Is the teacher correct?
