WebMar 4, 2016 · (2) In order to get the LCM as $168$ we got to distribute the remaining $14$ among these two numbers, being careful that the distribution has no common factors. (3) The factors of $14$ are $1,2,7,14$. So we take the first number as $12.1$, $12.2$, $12.7$, $12.14$ and the second number as $12.14$,$12.7$,$12.2$ and $12.1$ respectively WebLCM of 28 and 32 Using Prime Factorisation Method. In the Prime Factorisation method, the numbers can be expressed as the product of prime numbers. Here, 28 and 32 can be …

WebUsing the HCF and LCM formula, we can find the unknown value. HCF (a, b) × LCM (a, b) = a × b After substituting the values we get, 8 × 96 = 24 × b So the value of 'b' = 768/24 = 32. Therefore, the other number is 32. Note: Similarly, we can find the LCM of two numbers if we know the two numbers and the HCF using the same formula. WebHCF of 28 and 32 by Prime Factorisation Method In prime factorisation, the numbers can be expressed as the product of prime factors. Here, the numbers 28 and 32 are expressed as: 28 = 2 × 2 × 7 32 = 2 × 2 × 2 × 2 × 2 The common prime factors of 28 and 32 are 2 and 2. Therefore, HCF of (28, 32) = 2 × 2 = 4 HCF of 28 and 32 by Long Division Method self inventory questions
