Given numbers are 649, 780, 551, 328

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

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

Prime factors of 551 are 19 x 29

Prime factors of 328 are 2 x 2 x 2 x 41

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

Given numbers are 649, 780, 551, 328

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

Apply this formula for all numbers.

Step1:

LCM(649, 780) = 506220

GCD(649, 780) = ( 649 x 780 ) / 506220

= 649 / 780

= 649

Step2:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

Step3:

LCM(1, 328) = 328

GCD(1, 328) = ( 1 x 328 ) / 328

= 1 / 328

= 1

So, Greatest Common Divisor of 649, 780, 551, 328 is 1
