Question

can it be 5,673 divisible by 3 or 9 and why thx love 

Answer 1

Hi, Emma.

Yes, 5,673 is divisible by 3.

 

5673 ÷ 3 = 1891

 

You can find out if a number is divisible by 3 if the sum of its digits is a multiple of 3:

 

5673:   5 + 6 + 7 + 3 = 21    Since 21 is a multiple of 3  (3 x 7), then 5673 is divisible by 3.
