Question

If HCF of 144 and 280 is in the form 2n-4 . Find n

Answer 1

Hey mate! her is your answer,

If we Solve the LCM of 144 and 280 then,

$144 \div 2 = 72 \\ 280 \div 2 = 140.$

So then the HCF of 144 and 280 is 2.

so n is 3,how??

$2n - 4 = 2 \\ if \: n = 3 \\ 2 \times 3 - 4 = 2 \\ 6 - 4 = 2.$

Hope this will help you.
