The largest number that divides both 27 and 40 is called the greatest common divisor (GCD). The GCD of 27 and 40 is 1, since they have no common factors other than 1. Thus, the largest number that goes into both 27 and 40 is 1.
Nothing - as there is no number that goes into both 9 and 40. Only 1 or 3 goes into 9, and 40 is not divisible by 3 (either 39 or 42 are nearest). So it stays at 9 / 40
1 is the only number that goes into 29 and 40.
The number is 1.
The HCF of 38 and 40 is 2
