Updated: 11/2/2022

The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.

What is the HCF and LCM of the numbers 526 and 213?

hcf: 1 lcm: 112,038

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

Can HCF and LCM of two numbers be 27 and 288?

No. The LCM MUST be a multiple of the HCF.

What are the four methods to find LCM and HCF?

hcf or gcf. first write the numbers the number can be multiplied to get it,you will have more than one or two numbers and when you see you have the number in a row then look for the highest number in all row .LCM do same as hcf but the numbers you got just multiply.try 2,4,16,24,48 you must get for LCM get 144 and for hcf or gcf you must get 24.

Can two numbers have 16 as their HCF and 380 as their 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.

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.

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

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.

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 .

If 13 is HCF of 2 number whose product is 1690 find the LCM?

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.

What is the HCF and LCM of the numbers 526 and 213?

hcf: 1 lcm: 112,038

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 HCF if Lcm is 108?

Divide the product of the original numbers by 108, the LCM. The result will be the GCF.
