None!!! Because '171' is NOT an EVEN number. Remember even numbers end in 0,2,4,6,and 8. Since '171', does not end in 0,2,4,6 or 8 , then it is not an even number, so it will not divide evenly. NB However, you can divide '171' by '2' , and the answer is 85.5 or 85 1/2
54
The numbers 1, 3 and 9 all go into both 72 and 171.
HCF(54, 16) = 2
6 and 9 both go into 54.
174 =============== 18 = 15+3 54 = 18x3 57 = 54+3 171= 57x3 174= 171+3
