4.
Take m = 196 mm and n = 168 mm,
Here m > n.
196 - 168 = 28
168 - 28 = 140
140 - 28 = 112
112 - 28 = 84
84 - 28 = 56
56 - 28 = 28
28 - 28 = 0
The length of the side of the biggest square is 28 mm.

56 and 12
Take m = 56 and n = 12, Here m > n.
56 - 12 = 44
44 - 12 = 32
32 - 12 = 20
20 - 12 = 8
12 - B = 4
8 - 4 = 4
4 - 4 = A
The HCF of 56 and 12 is 4.
7.
Let number be m & n
m > n
We do m – n & the result of subtraction becomes new ‘m’.
if m becomes less than n, we do n – m and then assign the result as n.
We should do this till m = n. When m = n then ‘m’ is the HCF.
42 and 70 now m = 70, n = 42 70 – 42 = 28,
now m = 42, n = 28 42 – 28 = 14,
now m = 28, n = 14 28 – 14= 14,
now m = 14, n = 14
We stop here as m = n
∴ HCF of 42 & 70 is 14
8.
The HCF of 455 and 26 is 13
