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.
3 and 9.
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 .
HCF = 3... LCM = 18 !
5 and 10 lcm- 10 and hcf= 5

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 .
To find the LCM of two numbers, you multiply them together and divide by the HCF. In this case one of the numbers is 1 and so the HCF can only be 1. Thus all we have to do is multiply the numbers together: 1x3 = 3 And therefore the LCM of 1 and 3 is 3.
