If the product oftwo numbers is 810 if there HCF IS 9 FIND LCM?
if the product of two numbers is 810 if there hcf is 9 find Lcm
If the HCF and LCM of two numbers are 17 and 102 respectively and the HCF and LCM of two other numbers are 68 and 476 respectively then find the sum of the HCF and LCM of these four numbers?
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 .
What is the HCF and LCM of 3 and 18?
HCF = 3... LCM = 18 !
Can the HCF of two numbers be a factor of their LCM?
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.
The LCM of two numbers is twice their HCF?
5 and 10 lcm- 10 and hcf= 5
The product of two number is 20736 and their HCF is 54 find the LCM?
LCM = Product/HCF = 384
If the product oftwo numbers is 810 if there HCF IS 9 FIND LCM?
if the product of two numbers is 810 if there hcf is 9 find Lcm
If LCM and HCF is known of 2 number along with 1 number can you find second number?
Yes: product of a & b = LCM x HCF so b = (LCM x HCF)/a
How do you find sets of two numbers if HCF and LCM are known?
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.

What is the LCM of 10and20 to their hcf?
LCM is 20 and the hcf is 10
What is the HCF and LCM of 3 and 18?
HCF = 3... LCM = 18 !

HCF is 60 and the LCM is 360
What is the HCF and LCM of 42 and 84?
hcf = 42, lcm = 84.
What is the HCF and the LCM of 144 and 192?
