The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 969 are 3 x 17 x 19

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 551 are 19 x 29

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

Given numbers are 648, 969, 276, 551

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

Apply this formula for all numbers.

Step1:

LCM(648, 969) = 209304

GCD(648, 969) = ( 648 x 969 ) / 209304

= 648 / 969

= 648

Step2:

LCM(3, 276) = 276

GCD(3, 276) = ( 3 x 276 ) / 276

= 3 / 276

= 3

Step3:

LCM(3, 551) = 1653

GCD(3, 551) = ( 3 x 551 ) / 1653

= 3 / 551

= 3

So, Greatest Common Divisor of 648, 969, 276, 551 is 1
