Pick three.
To have an odd number of factors, the number must be a square. The only squares between 80 and 100 ()inclusive) are 81 and 100 but 81 does not have a factor of 5, and 100 has 9 factors. Thus the problem (as stated) has no solution. The numbers which have a factor of 5 must end in 0 or 5; the only numbers between 80 and 100 (inclusive) which match this criteria are {80, 85, 90, 95, 100}, which have {10, 4, 12, 4, 9} respectively. If you meant 3 PROPER factors (ie all the factors excluding the number itself), then 85 and 95 both have 3 proper factors.
9 = 1, 3, 9 4 = 1, 2, 4
To find the HCF of two numbers you first need to write them as the product of their prime factors: 36 = 2x2x3x3 40 = 2x2x2x5 The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiplying these together gives 4. Therefore, the HCF of 36 and 40 is 4. HCF(40, 36) = 4 The HCF (or GCF, greatest common factor) of two numbers can never be greater than the difference between the number
