3. Find the GCF of 16, 20 and 36. Solution: 16 =2×2× 2 × 2 20 =2×2× 5 36 =2×2× 3 × 3 Common factors = 2, 2 GCF(16, 20, 36) = 2 × 2 = 4 4. What is the GCF of 45 and 75 using the prime factorization method?
prime_factors函数: 该函数接收一个整数n,并返回其质因数分解结果,结果以字典形式表示,键为质因数,值为该质因数的幂次。 gcf函数: 首先对两个数a和b分别进行质因数分解。 然后找出两个数的共同质因数,并保留每个质因数的最小幂次。 最后,根据保留的质因数和幂次计算GCF。 示例使用: 示例中计算了56和98...
