Given numbers are 551, 780, 764, 349

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

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

Prime factors of 764 are 2 x 2 x 191

Prime factors of 349 are 349

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

Given numbers are 551, 780, 764, 349

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

Apply this formula for all numbers.

Step1:

LCM(551, 780) = 429780

GCD(551, 780) = ( 551 x 780 ) / 429780

= 551 / 780

= 551

Step2:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 551, 780, 764, 349 is 1
