Question

The h.c.f and l.c.m of two number are 14 and 84 if one number is 42 find an other

Answer 1

Hey... I think this can be ur answer!!
____________________________

Hcf = 14
LCM =84

Hcf *LCM =a*b(product of two numbers)
14*84 = 42*b
b=84*14/42
b=28

So the second no. Is 28

Answer 2

Answer:

The HCF and LCM of two number are 14 and 84 if one number is 42 then the another number is 28

Step-by-step explanation:

Given :

• the HCF of two numbers = 14
• The LCM of two numbers = 84
• One of the two numbers is 42

To Find :

Another Number

Solution :

Since we are given HCF and LCM of the two numbers which are 14 and 84

one of the number is 42.

Let the another number is 'a'.

Since we know that

LCM x HCF = The Product of Both the numbers

$14\ \text{ x}\ 84 = 42 \ \text{x}\ a$

$a=\frac{14\ \text{x}\ 84}{42}$

$a=\frac{84}{3}=28$

we have calculated that the another number is 28

Hence both the numbers are 42 and 28.
