Question

What is the greatest number divides 17,42 and 93 and leaves remainder 4,3 and 15?

Answer 1

Answer:

13

Step-by-step explanation:

To find the answer, first subtract 4 from 17, 3 from 42 and 15 from 93 as we will be able to find out the exact nos. that can be divided by that no. getting rid of the remainders.

So, the nos. we get are 13, 39 and 78.

The HCF of these nos. is 13, which you can get from prime factorisation method.
