Given numbers are 406, 764, 628, 563

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 764 are 2 x 2 x 191

Prime factors of 628 are 2 x 2 x 157

Prime factors of 563 are 563

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

Given numbers are 406, 764, 628, 563

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

Apply this formula for all numbers.

Step1:

LCM(406, 764) = 155092

GCD(406, 764) = ( 406 x 764 ) / 155092

= 406 / 764

= 406

Step2:

LCM(2, 628) = 628

GCD(2, 628) = ( 2 x 628 ) / 628

= 2 / 628

= 2

Step3:

LCM(2, 563) = 1126

GCD(2, 563) = ( 2 x 563 ) / 1126

= 2 / 563

= 2

So, Greatest Common Divisor of 406, 764, 628, 563 is 1
