163-3 =160
243-3=240
160= 2*2*2*2*2*5
240 = 2*2*2*2*3*5
HCF = 2^4*5
=80
243-3=240
160= 2*2*2*2*2*5
240 = 2*2*2*2*3*5
HCF = 2^4*5
=80

The largest number that divides 163 and 243 leaving 3 as the remainder is 80.
Given: The numbers 163 and 243
To Find: The largest number divides 163 and 243 leaving 3 as the remainder.
Solution:
- To find the largest number which divides 163 and 243 leaving the remainder 3 in each case, we need to think about HCF.
- Now, it is said that 3 should be left as a remainder, so we need to subtract 3 from both the numbers before finding their HCF.
We are given the numbers 163 and 243. Subtracting 3 in each case we get,
163 - 3 = 160 and 243 - 3 = 240
So, we shall find the HCF of the numbers 160, and 240.
The prime factorization of 160 and 240 can be given as,
160 = 2 x 2 x 2 x 2 x 2 x 5
240= 2 x 2 x 2 x 2 x 3 x 5
⇒ HCF = 2 x 2 x 2 x 2 x 5
= 80
Hence, the largest number that divides 163 and 243 leaving 3 as the remainder is 80.
