The answer is 6 and 36
6 and 36 12 and 18
12 and 18
6 and 36
The GCF is 36.
6 and 36 12 and 18
The LCM of 3, 15 and 36 is 180.
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.
HCF(36, 50) = 2LCM(36, 50) = 180
First you need to split the numbers into their prime factors: 36 = 2x2x3x3 40 = 2x2x2x5 The next step is to identify the HCF. In this case the HCF is 4. Finally, you multiply the numbers together and divide by the HCF: 36x40/4 = 360 And so the LCM of 36 and 40 is 360.
LCM is least common multiple of two or more numbers. LCM of 18 and 36 is 36.
I have been preparing for my GRE and have been practicing similar questions from www.examville.com The other number = HCF * LCM / Given number = 4 * 576 / 64 = 36
