lcm(9, 12) = 36; hcf(9, 12) = 3.
Write 100 and 120 in their prime compositions in power form: 100 = 223052 120 = 233151 For hcf, take lowest power of each prime across the compositions; for LCM, take highest powers: hcf = 223051 = 4 x 1 x 5 = 20 LCM = 233152 = 8 x 3 x 25 = 600
It's kind of an inverse relationship. The product of the GCF and LCM of two numbers is the same as the product of the original two numbers, so as the GCF increases, the LCM decreases and vice versa. LCM is divisable by HCF.
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.
They are 8 and 2520 respectively
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.
hcf: 1 lcm: 112,038
No. The LCM MUST be a multiple of the HCF.
LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.
5 and 10 lcm- 10 and hcf= 5
