Giant Forest, famed for its giant sequoia trees, is within Sequoia National Park. The forest, at over 6,000 feet (1,800 m) in elevation, is located in the western Sierra Nevada of California. Four out of the ten largest trees by volume on the planet are said to be within the Giant Forest. The largest, the General Sherman tree, measures 36.5 feet (11.1 m)
Largest known prime number Largest known prime number The largest known prime number () is 2 − 1, a number with 23,249,425 digits. It was found by the Great Internet Mersenne Prime Search (GIMPS) in 2017. Euclid proved that there is no largest prime number, and many mathematicians and hobbyists continue to search for large prime numbers. Many of the largest known primes are Mersenne primes. , the seven largest known primes are Mersenne primes. The last sixteen record primes were Mersenne primes. The fast Fourier transform implementation of the Lucas–Lehmer primality test for Mersenne numbers is fast compared to other known primality tests
