Given numbers are 782, 394, 280, 405

The list of prime factors of all numbers are

Prime factors of 782 are 2 x 17 x 23

Prime factors of 394 are 2 x 197

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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 782, 394, 280, 405

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

Apply this formula for all numbers.

Step1:

LCM(782, 394) = 154054

GCD(782, 394) = ( 782 x 394 ) / 154054

= 782 / 394

= 782

Step2:

LCM(2, 280) = 280

GCD(2, 280) = ( 2 x 280 ) / 280

= 2 / 280

= 2

Step3:

LCM(2, 405) = 810

GCD(2, 405) = ( 2 x 405 ) / 810

= 2 / 405

= 2

So, Greatest Common Divisor of 782, 394, 280, 405 is 1
