Question

The hcf of two number is 27 and their LCM is 162 .if one of the number is 81 find the other

Answer 1

Answer:

54

Step-by-step explanation:

formula is

LCM × HCF = FIRST NUMBER × SECOND NUMBER

SO

162 × 27 = 81 + SECOND NO

SECOND NO = 162×27/81= 162/3=54

Answer 2

Answer:

Step-by-step explanation:

HCF(a,b) ×LCM(a,b) = Product of a and b

27×162 = 81×b

b = (27×162)/81

b = 54
