You can crack it by taking 980,960 or 940and adding 1 in the end as these values are the only ones that are divisible by 20 in 900 range, its easier just to divide using calc and check

K(lcm of 3,4,6,15,20) + s , where s is the common remainder (ie 1) K*60 +1 K=0,1,2,3 and so on. So when k=16 we get the highest 3 digit no. Ie - 960+1= 961 So sum of digits = 16
