Given numbers are 551, 307, 780, 654

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 307 are 307

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

Prime factors of 654 are 2 x 3 x 109

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

Given numbers are 551, 307, 780, 654

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

Apply this formula for all numbers.

Step1:

LCM(551, 307) = 169157

GCD(551, 307) = ( 551 x 307 ) / 169157

= 551 / 307

= 551

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 654) = 654

GCD(1, 654) = ( 1 x 654 ) / 654

= 1 / 654

= 1

So, Greatest Common Divisor of 551, 307, 780, 654 is 1
