Answer:
6160
Step-by-step explanation:
If you do not understand my solution, send a picture of how your teacher does it and I will guide you in the same style as your teacher.
you have numbers: 16 28 40 77. I will write each number in each line and show its multiple numbers: Now that if you multiply the numbers I write, you get the same number. For example, 2*2*2*2 = 16 (same for the rest)
16: 2 2 2 2
28: 2 2 7
40: 2 2 2 5
77: 7 11
From the above, we pick 2*2*2*2*5*7*11 = 6160
I got that by picking a number comprised of factors that appear in at least any of the numbers 16 28 40 77
