The answer is below:
As a string, the largest number is 7111111.
There is no such number. Since if x were the largest multiple of 3 and 7 then what about 2x? 2x would be a multiple of 3 since x is a multiple of 3; 2x would be a multiple of 7 since x is a multiple of 7; and 2x is bigger than x. So x cannot be the largest.

write the largest number you can make using each of the digits 7,1,0,2, and 9 just once
9876543
4- last two digits are a multiple of 4 7-take the last digit and subtract it from the rest of the number and if multiple of 7 (including 0) 8- last three digits are multiple of 8
974. If you mean the largest one with ONLY the digits 4 and 7, then 774. If it can only contain 7 and 4 but doesn't have to have both, then 777.
To create the largest number using the digits 5, 3, 1, 4, and 7, arrange them in descending order. The largest number you can form is 75431.
the largest five digit number that can be formed using the digits 7 and 9 is 97,000
87,542 is.
It's a multiple of 7 (17 x 7) but not 3 (the digits 119 don't add up to 3)
