Given numbers are 355, 551, 646, 581

The list of prime factors of all numbers are

Prime factors of 355 are 5 x 71

Prime factors of 551 are 19 x 29

Prime factors of 646 are 2 x 17 x 19

Prime factors of 581 are 7 x 83

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

Given numbers are 355, 551, 646, 581

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

Apply this formula for all numbers.

Step1:

LCM(355, 551) = 195605

GCD(355, 551) = ( 355 x 551 ) / 195605

= 355 / 551

= 355

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 355, 551, 646, 581 is 1
