24
Finding the prime factors of numbers
23400=3*3*2*2*2*5*5*13
272304=3*3*2*2*2*2*31*61
205248=3*2*2*2*2*2*2*1069
Now HCF=3*2*2*2=24

i think the 1st number is 234000...

ok solve it as it is given

There is a trick to solve this type of qus
to find the largest number that will divide given numbers say X1,X2,...Xn so as to leave the same remainder in each case , we find the HCF of positive difference of numbers ie X1-X2 , X2-X3,... and so on.


solving this qus we will get the ans 8....
