Question

The hcf and lcm of two numbers are 3 and 2730. If one of the no is 78 find second no

Answer 1

LCM(a,b) =( a * b) /HCF (a, b)

b = 2730/(78*3)

b = 11.67

Answer 2

Step-by-step explanation:

LCM * HCF = PRODUCT OF TWO NUMBER

3 × 2730 = 78× X

X = (3×2730)/78

X = 105

105 IS THE SECOND NUMBER
