WebThe product of these divisors gives the LCM of 15 and 25. Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 15 and 25. Write this prime number (3) on the left of the given numbers (15 and 25), separated as per the ladder arrangement. Step 2: If any of the given numbers (15, 25) is a multiple of 3, divide it ... WebSep 30, 2024 · Questions Based on finding the HCF and LCM. Question 1: Find the LCM and HCF of 135 and 225. Solution: Here, we will find the LCM and HCF by prime factorization method. ... Here LCM of 12,15 and 18 = 180. On dividing 10000 by 180 the remainder is 100. So, the required least number of five digit = 10000 -100 + 180 = 10080.
WebTo find the LCM of 6, 12, and 15 using prime factorization, we will find the prime factors, (6 = 2 1 × 3 1 ), (12 = 2 2 × 3 1 ), and (15 = 3 1 × 5 1 ). LCM of 6, 12, and 15 is the product of prime factors raised to their respective highest exponent among the numbers 6, 12, and 15. ⇒ LCM of 6, 12, 15 = 2 2 × 3 1 × 5 1 = 60. WebDec 27, 2024 · One simple approach is to note that the HCF has to be a factor of $18$ and there are only $6$ of those to try. We also know that the product of the HCF and LCM is $18x$ so we can make a table $$\begin {array} {r r r r}HCF&LCM&18x&x\\ \hline 1&121&121&NA\\ 2&122&244&NA\\ 3&123&369&NA\\ 6&126&756&42\\ …
WebFind the LCM of the fractions 2/5, 4/7 and 6/11. Solution: Given fractions: 2/5, 4/7 and 6/11 As we know, the formula to find the LCM of fractions is: LCM of fractions = LCM of Numerators/HCF of Denominators .. (1) Thus, the LCM of Numerators = LCM (2, 4, 6) = 12. HCF of denominators = HCF (5, 7, 11) = 1 Now, substitute the values in (1), we get WebNow, divide 42 by 30 and get the HCF of 30 and 42 by performing the division method. When you get the remainder zero then that divisor i.e., 6 is the HCF of given numbers. Thus, HCF of 30 and 42 is 6. If you want to …
WebSolution: Step 1: Break down into prime factors. 16 = 2 x 2 x 3 = 22 x 3 32 = 2 x 2 x 2 x 2 = 24 Step 2: Identify similar factors. Both numbers have 22 as their factors. Step 3: Multiply the common factors. 22 = 2 x 2 = 4 Hence 4 is the HCF of 16 and 32 . To learn more about LCM and HCF, head over to the LCM calculator and GCF calculator.
WebJan 25, 2024 · so first we find LCM ( 6, 10). We know from above that their HCF is 2, so the LCM is 6 ⋅ 10 ÷ 2 = 30. Thus. The Euclidean algorithm gives HCF ( 30, 15) = 15, so LCM ( 30, 15) = 30 ⋅ 15 ÷ 15 = 30.
