Show that any great odd integer is of the shape 6q & 1, or perhaps 6q & 3, or perhaps 6q & 5, exactly where q can be some integer. An army dependant of 616 members is to march behind an army music group of 32 members within a parade. Both groups are to march inside the same number of columns. Precisely what is the maximum range of columns in which they can mar? Sol. Tips: Find the HCF of 616 and 32

3.

Use Euclid's division lemma to show that the square of any positive integer will either be of the type 3m or perhaps 3m & 1 for a few integer m. [Hint: Let times be virtually any positive integer then it is of the form 3q, 3q + 1 or perhaps 3q & 2 . Right now square these and show they can be rewritten in the contact form 3m or perhaps 3m & 1 . ]

5.

Use Euclid's division lemma to show the fact that cube of any positive integer features the form 9m, 9m & 1 or perhaps 9m & 8.

a few.

Consider the numbers 4n, where in is a natural number. Verify whether there exists any value of in for which 4n ends while using digit actually zero.

6. several. 8. 9. 10. 11. 12.

Find the LCM and HCF of 6th and 20 by the excellent factorization technique. Find the HCF of 96 and 404 by prime factorization method. Therefore, find their LCM. Locate the HCF and LCM of six, 72 and 120, using the prime factorization method. Discover the value of y if the HCF of 210 and fifty-five is expressible in the type 210 back button 5 + 55y Prove that no number of the type 4K + 2 can be a best square. Share each amount as a item of its prime elements: (i) a hundred and forty (ii) one hundred and fifty six (iii) 3825 (iv) 5005 (v) 7429 Find the LCM and HCF of the following pairs of integers and validate that LCM Г— HCF = merchandise of the two numbers. (i) 26 and 91 (ii) 510 and 92 (iii) 336 and 54
