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

The two numbers that have a least common multiple (LCM) of 54 and a highest common factor (HCF) of 3 are 27 and 18. The LCM is the smallest common multiple of the two numbers, while the HCF is the largest common factor. In this case, 27 and 18 have a LCM of 54 (27 x 2) and a HCF of 3 (3 x 3).
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 .
