24*6= 16 777 216
8 * 2 097 152 = 16 777 216
The largest digits number with only 2 digits alike is 99
You go for 99.
If the number is even, it is a multiple of 2 If the sum of the digits make a number divisible by 3, the number is a multiple of 3 If the number ends in 5 or 0, the number is a multiple of 5 If the number is divisible by 2 and 3, the number is a multiple of 6 If the sum of the digits make a number divisible by 9, the number is a multiple of 9
The largest number you could make with ONLY the digits 2, 6, and 4, assuming the use of exponents, is 2 to the power of 4 to the power of 6 = 2^(4^(6)) = 24096 this equals 1.044 X 101233 Without the use of exponents or additional symbols, the largest number you could make would of course be 642.
write the largest number you can make using each of the digits 7,1,0,2, and 9 just once
The unit digits are 2/4/6/8/0
Divisibility Rules 2 if it is even 3 if the sum of digits is a multiple of 3 4 if the last two digits is a multiple of 4 6 if it is divisible by 2 and 3 8 if the last three digits is multiple of 8
72
97632 is the largest number containing these digits. To make the largest number simply order the numbers in descending order. As it happens this results in an even number so nothing further is necessary.
Yes, yes, and no. 3- sum of digits must be multiple of 3. 6- sum of digits must be multiple of 3 and number must be even (multiple of 2). 9- sum of digits must be multiple of 9. (The sum of the digits here is 21.)
98
73 is the largest 2 digit number that is both prime and has prime numbers for both of its digits.
