Given numbers are 621, 222, 551, 864

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 222 are 2 x 3 x 37

Prime factors of 551 are 19 x 29

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

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

Given numbers are 621, 222, 551, 864

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

Apply this formula for all numbers.

Step1:

LCM(621, 222) = 45954

GCD(621, 222) = ( 621 x 222 ) / 45954

= 621 / 222

= 621

Step2:

LCM(3, 551) = 1653

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

= 3 / 551

= 3

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 621, 222, 551, 864 is 1
