Question

If the lcm and hcf of 2 numbers are 78 and 13 respectively, the product of 2 numbers can be expressed as

Answer 1

let first no. be x
and second no. be y

x=26
y=39
x*y=26*39=1014

Answer 2

Answer:

Given: LCM and HCF of 2 numbers are 78 and 13 respectively.

Using Property : Product of two numbers = $HCF \times LCM$

then,

Product of 2 numbers= $78 \times 13 =1014$

Since, HCF  is  equal to 13 which means both the numbers have 13 in common.

We can write LCM = 78 as $2\cdot 3 \cdot 13$

then,

we have the numbers $(13\cdot 2 , 13 \cdot 3)$ and $(13, 13\cdot3\cdot2)$ or $(26 ,39)$ and (13 ,78).

therefore, the product of 2 numbers can be expressed as (26, 39) and (13, 78)
