Given numbers are 629, 398, 732, 780

The list of prime factors of all numbers are

Prime factors of 629 are 17 x 37

Prime factors of 398 are 2 x 199

Prime factors of 732 are 2 x 2 x 3 x 61

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

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

Given numbers are 629, 398, 732, 780

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

Apply this formula for all numbers.

Step1:

LCM(629, 398) = 250342

GCD(629, 398) = ( 629 x 398 ) / 250342

= 629 / 398

= 629

Step2:

LCM(1, 732) = 732

GCD(1, 732) = ( 1 x 732 ) / 732

= 1 / 732

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 629, 398, 732, 780 is 1
