Question

check if the first number is divisible by the second. ( think of the co- prime factors of the divisor) 4000 by 30​

Answer 1

$Given \: numbers \: 4000 \: and \: 30$

Finding HCF of 4000 and 30:

30|4000| 133

****3990

____________

******10| 30| 3

*********30

_____________

**********(0)

$HCF\:of \: 4000 \:and \: 30 = 10$

$Now , \frac{4000}{30}$

$= \frac{ 400 \times 10}{3 \times 10}$

$= \frac{400}{3}$

Therefore.,

$\red{ 4000 \:is \: not \:divisible \:by \: 30 }$
