The factor pairs of 88 are:
1 x 88
2 x 44
4 x 22
8 x 11
88
There is only one number that equals 88. That number is . . . . . 88.
How about: 83+5 = 88 and 59+29 = 88 as two examples
2 and 11
2 and 11
55 + 33
8 x 11 = 88
43,45
You need at least two numbers to find a GCF.
41 + 47
HCF(365, 88) = 1. The two numbers are coprime.
It is not possible to give a sensible answer to this question. A common multiple refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
