Question

what is the hcf of 405,783,513​

Answer 1

Step-by-step explanation:

Firstly, let us find the HCF of 783 and 513,

783 = 513 × 1 + 270

513 = 270 × 1 + 243

270 = 243 × 1 + 27

243 = 27 × 9 + 0

So, 27 is the HCF of 783 and 513.

Now, let's find the HCF of 405 and 27,

405 = 27 × 15 + 0

So, 27 is the HCF of 405 and 27.

Hence the HCF of all three numbers 405, 513 ,and 783 is 27.
