Answer 1

Hello dear, I can help you.

So, to find the greatest number to divide them leaving remainders 1 and 3 respectively, we should find the HCF of:
Number-remainder. Ok now let's solve the questions.

1)HCF of 781-1 i.e. 780
=13

So it was easy. Now lets solve the 2nd question.

2)HCF of 458-3 i.e. 455
=13

Thanks.

Hope it helps.
