Find the greatest number which divides 285 and 1249 leaving remainder 9 and 7 respectively

Ans: 138

Step-by-step explanation:

subtraction 9 and 7 from 285 and 1249

1242=2 x 3 x 3 x 3 x 23

so HCF of 276 and 1242

=2*3*23=138

hence greatest number which divides 285 and 1249 leaving remainder 9 and 7 respectively

=138
