Find the greatest number that will divide 43, 91 and 183 so as to leave the same remainder in each case.
Answer: Option
Explanation:
Required number = H.C.F. of (91 - 43), (183 - 91) and (183 - 43)
= H.C.F. of 48, 92 and 140 = 4.

What could be the value of x if HCF of 12, 24, x is as same as GCD of 18, 36 and x?

1.91-43 = 48, 183-91 = 92, 183-43 = 140.
2.92-48 = 44, 140-92 = 48, 140-48 = 92.
For every time we eliminating uncommon Factors.

Find the highest number which divides 25 and 29 equally leaving 5 in each case.

I think 43 and 91 are prime numbers.
Prime numbers don't have factors, to find H.C.F we need factors, for that we are subtracting numbers to get non-prime numbers.
