WebClass 10th Maths Ch1 Real Number:- Can two numbers have 16 as their HCF and 380 as their LCM?#shorts #class10maths #realnumbers #hcf #lcm #hcfandlcm WebOct 10, 2024 · HCF is the Highest common factor between two numbers and LCM is the Lowest common multiple of those numbers. So, for a pair of numbers, LCM must be completely divisible by the HCF of those two numbers. Therefore, if two numbers have 16 as their HCF and 380 as their LCM then, 380 must be completely divisible by 16. Now, … bird box douglas

WebSolution : No , it is not possible Reason : HCF must be a factor of LCM . here 18 is not factor of 760. Was this answer helpful? 0 0 Find All solutions for this book RS Agarwal RS Agarwal Exercise 1A Similar questions The product of two numbers whose HCF is 18 is 5832 How many pairs of numbers satisfy the above conditions? Medium View solution > WebHCF of two numbers is a factor of the LCM of those numbers. Thus, we cannot have two numbers whose HCF is 16 and LCM is 380. Because, when we divide 380 by 16, we get a remainder of 12. Thus, 16 is not a factor of 380. Hence, we cannot have two numbers whose HCF is 16 and LCM is 380. HOPE IT HELPS!! WebNow, HCF divides both numbers. Further, both numbers perfectly divide LCM. So, HCF must perfectly divide LCM. In other words, for LCM÷HCF, remainder must be zero. Here, … dally m 2023
