Lies! It is composite: 1, 3, 57, 171
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
The number 171 is composite because it can divide not just by 1 and 171 but 3, 9, 19 and 57.
If the two numbers have no factors in common then they are relatively prime. 152 = 2 x 2 x 2 x 19 171 = 3 x 3 x 19. They both have 19 as a factor and therefore 152 and 171 are NOT relatively prime.
171 is not "divisable" by anything, because there is no such word. However, it's prime factorisation is: 171 = 3*3*19
171 = 3 x 3 x 19.3 x 3 x 19 = 171
no, the GCF is 19.
