Q33. Use Euclid's Algorithm to find the HCF of 595 and 252 and express it in the form 595 m + 252n.
[ Ans. HCF (595, 252) = 7 and 7 = 595 (–11) + 252 (26) Here m = – 11, n = 26]
Q34. If d = HCF of a and b, then d = na + mb, where m and n are integers, i.e., HCF of a and b is linear combination of a and b. Verify the above result for a =384, b = 26, i.e., verify that HCF of 384 and 26 is a linear combination of 384 and 26.

Here 7^2 can be divided by 441 and then it is in form of 2^m * 5^n. But in book it is said as non terminating. Plz help me
441?(5^2*2^2*7^2) but we can first cancel the numerator by 7^2 and we get 9?(5^2*7^2)
