Answer 1

Answer:

9960

Step-by-step explanation:

given

the greatest four digit =9999

which is exactly divided by 8, 15and 20

so,

LCM of 8,15and 20=120

now we have to divide 9999 by120

=>9999÷120

here we get remainder 39

now

we have to subtract remainder from the greatest four digit number to find required number

hence:-

the greatest four digit number=9999-39=9960
