Find the greatest number which when divides 252, 1848, and 462 leaves the same remainder.
Explanation:
The greatest number which when divides a, b, and c leaves the same remainder = HCF [|a – b|, |b – c|].
The greatest number which when divides 252, 1848, and 462 leaves the same remainder
= HCF ((1848 – 252), (1848 – 462)) = 42.
Hence, option (b).
