Answer:
10
Step-by-step explanation:
first you need to find the prime factors of the three numbers
ex:
prime factor of 18= [tex]2*3*3[/tex]
prime of 24=[tex]2*2*2*3[/tex]
there is one 2 and one 3 in common
greatest common multiple 2*3=6
so the greatest common multiple is ten because it is the only one that can divide between all three evenly.
[tex]10=10/10=1\\20=20/10=2\\50=50/10=5[/tex]
so 10 is your answer
