Given that humans have been studying numbers for thousands of years, you might think we know everything about the number 3. But mathematicians recently discovered something new about 3: a third way to ...

When the sum of cubes equation is framed in this way, for certain values of k, the integer solutions for x, y, and z can grow to enormous numbers.

Sets of cubes 1. Find the set of perfect cubes that between them use each of the digits 0 to 9 at least once whose sum is as small as possible. What is the sum of your set of cubes? 2. Find the ...

Since 2025 is divisible by the sum of its digits (9), it qualifies as a Harshad number. 7. Triangular square: 45 = (9 x 10)/2. 2025 is the square of 45, which is also the 9th triangular number. 8.

There are now several numbers smaller than 1,000 without a sum of three cube solution, Sutherland explained, but he’s more interested in sums of three cubes that produce the number 3.

Hot on the heels of the ground-breaking ‘Sum-Of-Three-Cubes’ solution for the number 33, a team led by the University of Bristol and Massachusetts Institute of Technology (MIT) has solved the final ...
