To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get: 1690/13 = 130 And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.
HCF is 60 and the LCM is 360
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.
First you need to break the numbers into their prime factors. In this case we get: 63 = 3x3x7 21 = 3x7 The next step is to identify any common prime factors. In this case both have a 3 and a 7 as prime factors. Multiply these together and you get 3x7 = 21. This is the HCF. To find the LCM you just multiply the numbers together and divide by the HCF. 63x21/21 = 63 Thus 63 is the LCM.
No, that is the HCF. The LCM is 1800
Divide the product of the original numbers by 108, the LCM. The result will be the GCF.
To find the LCM, you multiply the numbers together and then divide by the HCF. In this case, we don't know the numbers, but we have the HCF (13) and we have the product of the numbers (1690). Thus all you do is divide 1690 by 13 to get: 1690/13 = 130 And thus the LCM of two numbers whose hcf is 13 and product is 1690 is 130.
LCM is 20 and the hcf is 10
HCF = 3... LCM = 18 !
HCF is 60 and the LCM is 360
hcf is 1 and LCM is 35
HCF is 48 and LCM is 576
hcf = 42, lcm = 84.
The HCF is: 2The LCM is: 2,520
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
To find the LCM of 110 and 20, you first need to break them up into their prime factors: 110 = 2x5x11 20 = 2x2x5 The next step is to identify the HCF. In this case the HCF will be 2x5 = 10. To find the LCM you multiply the numbers together and divide by the HCF: 110x20/10 = 220. Thus the LCM of 110 and 20 is 220.
hcf: 1 lcm: 112,038
