Given numbers are 780, 629, 430, 808

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 629 are 17 x 37

Prime factors of 430 are 2 x 5 x 43

Prime factors of 808 are 2 x 2 x 2 x 101

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

Given numbers are 780, 629, 430, 808

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

Apply this formula for all numbers.

Step1:

LCM(780, 629) = 490620

GCD(780, 629) = ( 780 x 629 ) / 490620

= 780 / 629

= 780

Step2:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 780, 629, 430, 808 is 1
