To find the Highest Common Factor (HCF) and Lowest Common Multiple (LCM) of two positive integers, we can follow these steps:1. Factorization of the Numbers: - Let's consider two positive integers, \( a \) and \( b \). -
HCF of co-prime numbers 4 and 15 was found as follows by factorisation : and since there is no common prime factor, so HCF of 4 and 15 is 0. Is the answ
HCF of 8 and 15 is the largest possible number which divides 8 and 15 without leaving any remainder. The methods to compute the HCF of 8, 15 are explained here.
HCF of co-prime numbers 4 and 15 was found as follows by factorisation:4 = 2 × 2 and 15 =3 × 5 since there is no common prime factor, so HCF of 4 and 15 is 0.Is the answer correct? If not, what is the correct HCF?
The HCF and LCM of two numbers is 9 and 459 respectively. If one of the number is 27, then the other number is( )?A. 153B. 150C. 459D. 135 相关知识点: 试题来源: 解析 A. 153 设另一个数为x。根据公式:两数乘积 = HCF × LCM,可得:27 × x = 9 × 459 解得:x = (9 × ...
The HCF of two or more numbers is the greatest number that divides each of them exactly. The LCM of two or more numbers is the smallest of the common multiples of those numbers. Learn more about how to find the HCF and LCM in this article.
