Question

Product of two numbers is 15870 and their HCF is 23 then their LCM will be

Answer 1

Answer:

The answer is 690

Step-by-step explanation:

Concept:       For any two numbers we know that

                   $\text{Product of the numbers}=\text{LCM}\times \text{HCF}$

Given

                 $\text{HCF}=23, \text{ product of numbers }=15870$

Thus using above result

,

                 $\Rightarrow 15870=23\times \text{LCM}\\\\\displaystyle \therefore \text{LCM}=\frac{15870}{23}=690$

Answer 2

Step-by-step explanation:

• let the two no. be X and Y

X*Y=15870

HCF= 23

LCM= ??

X*Y= LCM × HCF

15870= LCM × 23

15870/23 = LCM

=690
