To find the HCF (Highest Common Factor) and LCM (Lowest Common Multiple) of the numbers 404 and 96, we will use the Prime Factorization method. Let's go through the solution step by step.Step 1: Prime Factorization of 404 - Sta
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. ...
To find the other number when the HCF (Highest Common Factor) and LCM (Lowest Common Multiple) of two numbers are given, along with one of the numbers, we can use the formula:HCF × LCM = First Number × Second NumberGiv
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 ...
