Answer: 138
The number leaves remainder 9 when it divides 285. hence 285-9 will be a multiple of it. hence, 276 is a multiple of that number.
the number leaves remainder 7 when it divides 1249. hence, 1249-7 will be a multiple of it. Hence, 1242 is a multiple.
Greatest number which has 276 and 1242 as a multiple i.e. the HCF of 276 and 1242
= 138
