WebJan 1, 2014 · Worst-case complexity is still O(n2) for n-bit input, but actual implementations given input about 4096 bits long perform over 5.5 times as fast as the binary GCD on one computer architecture ... Greatest common divisors can be computed by determining the prime factorizations of the two numbers and comparing factors. For example, to compute gcd(48, 180), we find the prime factorizations 48 = 2 · 3 and 180 = 2 · 3 · 5 ; the GCD is then 2 · 3 · 5 = 2 · 3 · 5 = 12, as shown in the Venn diagram. The corresponding LCM is then 2 · 3 · 5 = 2 · 3 · 5 = 720. the range duvet sets and matching curtains https://migratingminerals.com
