Factors of 1776:
Another way to show love is to plant a tree. How about we plant a factor tree? Since 1776 has twenty different factor pairs, MANY possible factor trees could be planted. I chose to base this one on the fun fact that 1776 = 4 · 444:
- 1776 is a composite number.
- Prime factorization: 1776 = 2 × 2 × 2 × 2 × 3 × 37, which can be written 1776 = 2⁴ × 3 × 37
- 1776 has at least one exponent greater than 1 in its prime factorization so √1776 can be simplified. Taking the factor pair from the factor pair table below with the largest square number factor, we get √1776 = (√16)(√111) = 4√111
- The exponents in the prime factorization are 4, 1 and 1. Adding one to each exponent and multiplying we get (4 + 1)(1 + 1)(1 + 1) = 5 × 2 × 2 = 20. Therefore 1776 has exactly 20 factors.
- The factors of 1776 are outlined with their factor pair partners in the graphic below.

More About the Number 1776:
1776 is the hypotenuse of a Pythagorean triple:
576-1680-1776, which is (12-35-37) times 48.
1776 looks interesting in some other bases:
It’s 5115 in base7 because 5(7³) + 1(7²) +1(7) + 5(1) = 1776, and uh oh!
OO in base73 because 24(73) + 24(1) = 24(74) = 1776.
We’ve run out of letters in the alphabet to use as numbers, but I
will note that 37(47) + 37(1) = 37(48) = 1776.
