Given numbers are 705, 270, 346, 405

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 346 are 2 x 173

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 705, 270, 346, 405

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(705, 270) = 12690

GCD(705, 270) = ( 705 x 270 ) / 12690

= 705 / 270

= 705

Step2:

LCM(15, 346) = 5190

GCD(15, 346) = ( 15 x 346 ) / 5190

= 15 / 346

= 15

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 705, 270, 346, 405 is 1
