I assume you are looking for factors of 43 and 123. There is no common factor, other than 1. (43 is a prime number; 123 is not a multiple of 43.)
39, 41 and 43. or 123/3 -2, 123/3 and 123/3 +2
123.4651
The numbers are 39, 41 and 43.
43+n
The place value of the number 3 in 43 is three units.
Only the number one.
123
The only number that goes into 43 and 32 is 1, since they are co-prime.
39, 41 and 43. or 123/3 -2, 123/3 and 123/3 +2
43
8
1, 3, 43, 129.
They are: -39 -41 -43 = -123
43 goes 2.326 times (approx), 100 goes 0.43 times (exactly).
Yes to both.
123/3 - 2, 123/3 and 123/3 + 2 ie 39, 41 and 43.
43 is the only prime number in that list; 33 and 63 are both divisible by 3.
