Given numbers are 783, 830, 765, 457

The list of prime factors of all numbers are

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 830 are 2 x 5 x 83

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 457 are 457

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

Given numbers are 783, 830, 765, 457

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

Apply this formula for all numbers.

Step1:

LCM(783, 830) = 649890

GCD(783, 830) = ( 783 x 830 ) / 649890

= 783 / 830

= 783

Step2:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 783, 830, 765, 457 is 1
