The HCF of two or more numbers is the greatest number that divides each of them exactly. The LCM of two or more numbers is the smallest of the common multiples of those numbers. Learn more about how to find the HCF and LCM in this article.
The correct Answer is:B To find the second number given the HCF, LCM, and the first number, we can use the relationship between these values. The formula we will use is: HCF×LCM=First Number×Second Number 1. Identify the given values: - HCF = 16 - LCM = 160 - First Number = ...
Example:Consider this as an example; the LCM of \(12\) and \(15\) is \(60\). To find the LCM of numbers, first, you need to mention the multiples of each given number. Thus, the multiples of \(12=12, 24, 36, 48, 60, 72, 84…\) etc., ...
And, RHS = [(40 × 42 × 45) × LCM(40, 42, 45)]/[LCM(40, 42) × LCM (42, 45) × LCM(40, 45)] = [(75600) × 2520]/[840 × 630 × 360] LHS = RHS = 1. Hence verified. Example 2: Calculate the HCF of 40, 42, and 45 using LCM of the given numbers. ...
Find HCF and LCM of 404 and 96 and verify that HCF LCM Product of the two given numbers - Given: Number 404 and 96.To do: To Find HCF and LCM of 404 and 96 and verify that HCF$times$LCM $=$ Product of the two given numbers.Solution:Using the factor...
To answer this question, we have to find the least number which is exactly divisible by the given numbers 15, 20 and 25. That is the least common multiple of (15, 20, 25). LCM (15, 20, 25) = 300 So, we need 300 soldiers such that they stand in rows of 15, 20 , 25. ...
The greatest number by which x, y and z divisible and gives same remainder in each case, that number is HCF of (x–y), (y–z) and (z–x). There are two methods to find the Highest Common Factor (HCF) Division method Let we have three numbers .Pick the smaller one and divide ...
