Question

The LCM of two numbers is 36 and HCF is 2, if first number is 18 then second number is?

Answer 1

Answer:

let the no. be x

H.C.F × L·C·M = product of two numbers

36 × 2 = 18x

x = 36 × 2/18

∴ x = 4

∴ second number is 4

Step-by-step explanation:

Answer 2

Given :-

LCM of two numbers = 36

HCF of that numbers = 2

The first number= 18

To FinD :-

What is second number ?

Solution :-

Let the second number is x

We know that →

• LCM × HCF = Product of The numbers

So ,

36 × 2 = 18 × X

18X = 72

X = 72/18

x = 4

So, the second number is 4.
