Given:

  • We have been given three numbers, 1025, 1299 and 1575.

To Find:

  • We need to find the greatest number that will divide 1025, 1299 and 1575 leaving remainders 5, 7 and 11 respectively.

Solution:

We have been given three numbers, 1025, 1299 and 1575.

Inorder to find the greatest number that will divide 1025, 1299 and 1575 leaving remainders 5, 7 and 11 respectively, we need to subtract 5, 7 and 11 from 1025, 1299 and 1575 respectively and then find their HCF.

1025 - 5 = 1020

1299 - 7 = 1292

1575 - 11 = 1564

Now, we need to find the HCF of 1020, 1292 and 1564.

We can find the HCF of 1020, 1292 and 1564 by prime factorisation method.

Therefore, HCF of 1020, 1292 and 1564 is:

2 × 2 × 17

= 4 × 17

= 68

Hence, the required number is 68.
