Aptitude - HCF and LCM - If a number P divides another number Q exactly, we say that P is a factor of Q i.e. Q is a multiple of P.
The same thing happened in our problem. To find the time, when they will all change simultaneously, we have to find the LCM of (48, 72, 108). LCM (48, 72, 108) = 432 seconds or 7 min 12 sec So, after every 7 min 12 sec, all the signals will change simultaneously. ...
The sum of two non co–prime numbers added to their HCF gives us 91. How many such pairs are possible? 2 4 3 6 Choice C 3 CAT Number System: HCF LCM basics There are 2 numbers such that a > b, HCF (a, b) = h and LCM (a, b) = l. What is the LCM of a – b and ...
Example: Let us find the HCF and LCM of 6 and 8 to understand their relationship.Solution: The HCF of 6 and 8 = 2; The LCM of 6 and 8 = 24; The product of the two given numbers is 6 × 8 = 48. So, let us substitute these values in the formula that explains the ...
