The smallest number that when doubled contains all the same digits in a different order.
24 is the smallest example, 86 is the highest (unless both digits may be the same when you could have 22 & 88)
What is the smallest 7 digit number with only 2 digits that are the same and the numeral 5 in the 10 thousand place? 1050234
An eight digit number with one zero cannot remain the same when its digits are reversed. It must have an even number of 0s.
five digits number when you multiply by four is the same the number when you reversed it is 21978*4 = 87912
Two versions of this question have been merged ... the one that asks forthe smallest 5-digit number, and the one that asks for the largest.If we're talking integers (whole numbers), then-- the largest 5-digit number with no repeating digits is 98,765 .-- the smallest one is 10,234 .-- If decimals are included, then the largest number is the same,but the smallest one is .01234 .
There is no smallest number and no biggest number. Given any big number, however big, it is always possible to find one that is bigger (and the same with the smallest).
8 is the same as the sum of the digits of its cube, 512.
