Question

find the largest number which divides 220, 313 and 716 leaving remainder 3 in each cases

Answer 1

First we will subtract 3 from each no.-

220 - 3 = 217
313 - 3 = 310
716 - 3 = 713

Then, we will find the HCF of 217,310,713

217 = 7*31
310 = 2*5*31
713 = 23*31.

So, the HCF of 217,310,713 is 31.

So, therefore, the largest no. that divides 220,313, and 716 is 31.

Step 2

Find the HCF of 217,310

HCF = 31

Step 3

Find HCF of 31,713

HCF = 31 (Ans)
