Prime factorizationis a way of expressing a number as a product of itsprime factors. A prime number is a number that has exactly two factors, 1 and the number itself. For example, if we take the number 30. We know that 30 = 5 × 6, but 6 is not a prime number. The number 6 ...
(i) For the numbers 8, 9, and 25:1. Prime Factorization: - 8 = 2 × 2 × 2 = 23 - 9 = 3 × 3 = 32 - 25 = 5 × 5 = 52 2. Finding HCF: - There are no common prime factors among 8, 9, and 25. - Therefore, HCF = 1. 3. Finding LCM: - LCM is found by takin...
Prime and Composite Numbers Divisibility test for 2, 4 and 8 Divisibility test for 7 Highest Common Factor (HCF) We already know that a number which exactly divides two or more given numbers is the common factor of the given numbers. Infactorization, we intend to find the factors of a giv...
In this article, we will find HCF of two numbers using factorisation and division method, with the help of solved examples. Also, find the HCF of three numbers, here at BYJU’S.
Using Prime Factorisation to find HCF of two numbers The highest common factor ( H. C. F. ) of two or more numbers is the greatest or the largest among common factors. In other words, the H. C. F. of two or more numbers is the largest number that divides all the given numbers ex...
