MARK ME BRAINLINEST
Step-by-step explanation:
First we need to see how to find a number that gives remainder two when divided 5, 6, and 7 individually.
This can be found by considering the LCM of 5, 6, and 7. As these are relative prime, the LCM of them is simply 5 \times 6 \times 7 = 210.
So now any multiple of 210 added to 2 would give remainder 2 when divided by any of these three numbers 5, 6, and 7.
We need to find a multiple that gives greatest five-digit number when added to 2.
Try the division 105/210 and find the floor of it:
Integer part of 105210 is 476
Now consider 476×210+2=99962- the required five-digit number
