Find the LCM and HCF of 236 and 92 and very that as lcm into HCF product

Step-by-step explanation:

LCM is lowest common factor and HCF is highest common factor.

Given numbers are 236 and 92.

We can find it using prime factorization method.

Prime factorization of 236 = 2 x 2 x 59

Prime factorization of 92 = 2 x 2 x 23

HCF = 2 x 2 = 4

LCM = 2 x 2 x 59 x 23 = 5428

We know that,

LCM×HCF = product of two numbers

⇒ LCM×HCF = 5428×4 = 21712

⇒ product of two numbers = 236× 92 = 21712

Hence, proved.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
