HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
Divide the product of the original numbers by 108, the LCM. The result will be the GCF.
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.
No, 2 and 10 are factors of 20. The LCM of 2 and 10 is 10.
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.
Two or more numbers are needed to solve for HCF or LCM.
5 and 10 lcm- 10 and hcf= 5
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
HCF of 17 and 68 is 17 ..( Lowest Prime factor ) LCM Of 102 and 476 is 7*2^2*3*17 which is 1428 .. ==> Sum of HCF and LCM are 1428+17= 1445 .
if the product of two numbers is 810 if there hcf is 9 find Lcm
LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.
LCM=18=2*32 HCF(guess that is what u meant, highest common factor)=3 Possibilities: 3 and 18, 6 and 9, three or all of the numbers together. Note: 3 and 6 gives a LCM of 6 3 and 9 gives a LCM of 9 6 and 18 gives a HCF of 6 9 and 18 gives a HCF of 9 Three or four out of the numbers (3,6,9 and 18) will give you LCM of 18 and HCF of 3 as well.
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.
