Given numbers are 405, 850, 768, 453

The list of prime factors of all numbers are

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

Prime factors of 850 are 2 x 5 x 5 x 17

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 453 are 3 x 151

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

Given numbers are 405, 850, 768, 453

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

Apply this formula for all numbers.

Step1:

LCM(405, 850) = 68850

GCD(405, 850) = ( 405 x 850 ) / 68850

= 405 / 850

= 405

Step2:

LCM(5, 768) = 3840

GCD(5, 768) = ( 5 x 768 ) / 3840

= 5 / 768

= 5

Step3:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

So, Greatest Common Divisor of 405, 850, 768, 453 is 1
