Introduction

Pythagorean triplets are sets of three positive integers a, b, and c, such that a^2 + b^2 = c^2. These triplets are named after the ancient Greek mathematician Pythagoras, who is credited with their discovery. In this article, we will explore the concept of Pythagorean triplets and find the smallest number in the triplet whose largest member is 13.

What are Pythagorean Triplets?

Pythagorean triplets are sets of three positive integers a, b, and c, such that a^2 + b^2 = c^2. These triplets can be generated using various methods, including the use of Euclid's formula, which states that for any two positive integers m and n, with m > n, the following triplet is a Pythagorean triplet:

a = m^2 - n^2 b = 2mn c = m^2 + n^2

Finding Pythagorean Triplets with a Largest Member of 13

To find the smallest number in the Pythagorean triplet whose largest member is 13, we need to find all Pythagorean triplets whose largest member is 13. We can start by listing all possible values of c, which is the largest member of the triplet.

c = 13

Using Euclid's Formula to Find Pythagorean Triplets

We can use Euclid's formula to find Pythagorean triplets with a largest member of 13. We need to find values of m and n such that:

c = m^2 + n^2 c = 13

Solving for m and n

We can start by trying different values of m and n to find a solution. We can start with m = 3 and n = 2, which gives us:

a = m^2 - n^2 a = 3^2 - 2^2 a = 9 - 4 a = 5

b = 2mn b = 2(3)(2) b = 12

c = m^2 + n^2 c = 3^2 + 2^2 c = 9 + 4 c = 13

Verifying the Pythagorean Triplet

We can verify that this is indeed a Pythagorean triplet by checking if a^2 + b^2 = c^2.

a^2 + b^2 = 5^2 + 12^2 a^2 + b^2 = 25 + 144 a^2 + b^2 = 169 c^2 = 13^2 c^2 = 169

Conclusion

We have found a Pythagorean triplet with a largest member of 13, which is (5, 12, 13). This is the smallest number in the Pythagorean triplet whose largest member is 13.
