Given numbers are 621, 273, 68, 624

The list of prime factors of all numbers are

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

Prime factors of 273 are 3 x 7 x 13

Prime factors of 68 are 2 x 2 x 17

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 621, 273, 68, 624

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

Apply this formula for all numbers.

Step1:

LCM(621, 273) = 56511

GCD(621, 273) = ( 621 x 273 ) / 56511

= 621 / 273

= 621

Step2:

LCM(3, 68) = 204

GCD(3, 68) = ( 3 x 68 ) / 204

= 3 / 68

= 3

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 621, 273, 68, 624 is 1
