To find the HCF you first have to write the numbers as their prime factors:
36 = 2x2x3x3
75 = 3x5x5
The next step is to identify any common prime factors. In this case both numbers have 3 as a prime factor. Thus the HCF is 3.
To find the LCM you need to multiply the numbers together and divide by the HCF. 36x75/3 = 900
Thus the LCM of 36 and 75 is 900.
6 and 36 12 and 18
HCF is 60 and the LCM is 360
The GCF is 75.
The GCF is 18.
No, that is the HCF. The LCM is 1800
The LCM is 900.
lcm(9, 12) = 36; hcf(9, 12) = 3.
6 and 36
The GCF is 12.
36 and 6 18 and 12
The answer is 6 and 36
Their HCF is 1 and their LCM is 36
15 and 25
225 and 15, respectively.
Well, honey, the highest common factor (HCF) of 36 and 50 is 2, because that's the largest number that divides both of them evenly. And the least common multiple (LCM) is 900, which is the smallest multiple they both share. So, there you have it, darling!
