solution
subtract the remainders from the numbers
1249_7=1242
285_9=276
to find the common divisor wewill find the hcf
of the two new numbers 1242 and 276 using algorithm method
276) 1242 (4
1104
_____
138) 276 (2
276
___
×××
therefore, the hcf is 138
138 is the number which will divide 285 and 1249 leaving 9 and 7 as remainders
