Given numbers are 629, 340, 780, 395

The list of prime factors of all numbers are

Prime factors of 629 are 17 x 37

Prime factors of 340 are 2 x 2 x 5 x 17

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

Prime factors of 395 are 5 x 79

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

Given numbers are 629, 340, 780, 395

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

Apply this formula for all numbers.

Step1:

LCM(629, 340) = 12580

GCD(629, 340) = ( 629 x 340 ) / 12580

= 629 / 340

= 629

Step2:

LCM(17, 780) = 13260

GCD(17, 780) = ( 17 x 780 ) / 13260

= 17 / 780

= 17

Step3:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 629, 340, 780, 395 is 1
