The H.C.F of two equal positive integers k, k is :

This activity to determine H.C.F. of two given positive integers. (i) From the given numbers, subtract the smaller from the larger number. (ii) From the remaining numbers, subtract smaller from the larger. (iii) Repeat the subtraction process by subtracting smaller from the larger. (iv) Stop the process, when the numbers become equal. (v) The number representing equal numbers obtained in step (iv), will be the H.C.F. of the given numbers. Using the Activity , find the HCF of 40,16

Say True or False: The product of two negative integers is a positive integer.

Prove that two consecutive positive integers are always coprime.

The frequency distribution is given below. {:(x,k,2k,3k,4k,5k,6k),(f,2,1,1,1,1,1):} In the table, k is a positive integer, has a varience of 160. Determine the value of k.
