# What is the HCF and LCM of 500and 800?

hcf is 100

lcm is 4000

500 = 22 x 53

800 = 25 x 52

hcf = 22 x 52 = 100

lcm = 25 x 53 = 4000

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.

LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.

HCF - Highest Common Factor. LCM - Lowest Common Multiple.

The HCF and LCM of 16 and 108 are 4 and 432 respectively.

The HCF helps when reducing fractions. The LCM helps when adding or subtracting fractions.

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 .. ==&gt; Sum of HCF and LCM are 1428+17= 1445 .
