So our possible pairs are (6,6) , (6,18) , or (18,18) . But wait—only one of these pairs has both an LCM of 18 and a GCF of 6. That pair is (6,18) .
What is the LCM and HCF of 18?
Given that, LCM (a, 18) is 36 and HCF (a,18) is 2. One of the numbers is known to us as 18. a = 72/18 = 4.
What is the formula of LCM HCF?
L.C.M and HCF Important Formulas Product of two numbers (First number x Second Number) = H.C.F. X L.C.M. H.C.F. of a given number always divides its L.C.M. To find the least number which when divided by x, y and z leaves the remainders a, b and c respectively.
What happens when the LCM of two numbers is 18?
Explanation: If the LCM of the two numbers is 18, that means both numbers have to be factors of 18. So each number could be 1, 2, 3, 6, 9, or 18. If the GCF of the two numbers is 6, that means both numbers are divisible by 6. So each number could be 6, 12, 18, 24, etc. When we overlap these two restrictions,…
Is the LCM always divisible by HCF?
LCM is always divisible by HCF. Therefore, we divide LCM by HCF. We get 5. Now 5 can be written as a product as 5 and 1. Multiply this factor 5 with HCF 4 we get 20. Take this as on number. The other number is got by multiplying the other factor 1 with the HCF, which gives 4. The two numbers required are 20 and 4.
Can two numbers have 18 as their HCF and 380?
Answer Since HCF is 18 numbers can be assumed as 18x and 18y. ⇒ 380 = 2×5×2×19 ⇒ 380 is not divisible by 18 itself hence HCF 18 and LCM as 380 is not possible.
