Given numbers are 676, 646, 563, 807

The list of prime factors of all numbers are

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 646 are 2 x 17 x 19

Prime factors of 563 are 563

Prime factors of 807 are 3 x 269

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

Given numbers are 676, 646, 563, 807

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

Apply this formula for all numbers.

Step1:

LCM(676, 646) = 218348

GCD(676, 646) = ( 676 x 646 ) / 218348

= 676 / 646

= 676

Step2:

LCM(2, 563) = 1126

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

= 2 / 563

= 2

Step3:

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

= 1 / 807

= 1

So, Greatest Common Divisor of 676, 646, 563, 807 is 1
