As the number \(3\) is the only common factor for both the numbers \(12\) and \(15\), it is the largest number that divides both numbers.Hence, \(3\) is the required answer.LCM and HCF FormulaThe LCM and HCF Formula are discussed below:...
根据公式:两数乘积 = HCF × LCM,可得:27 × x = 9 × 459 解得:x = (9 × 459) / 27 计算过程: 9× 459 = 4131 4131 ÷ 27 = 153 验证: - **HCF验证**:将27和153分解质因数: 27 = 3 × 3 × 3 153 = 3 × 3 × 17 公共质因数为3 × 3 = 9(与题目条件一致)。 - ...
三个代数式的HCF(最高公因式)及LCM(最小公倍式)分别为pq^2及p^5q^4r,若第一个代数式及第二个代数式分别为pq^3r及p^3q^2,则第三个代数式为( )。 A. p^5qr B. p^2q^2r C. p^5q^4r^2 D. p^5q^4r 相关知识点: 试题来源: 解析 B 本题涉及最高公因式和最小公倍式的知识...
