The list of prime factors of all numbers are

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

Prime factors of 669 are 3 x 223

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 253 are 11 x 23

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

Given numbers are 621, 669, 740, 253

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

Apply this formula for all numbers.

Step1:

LCM(621, 669) = 138483

GCD(621, 669) = ( 621 x 669 ) / 138483

= 621 / 669

= 621

Step2:

LCM(3, 740) = 2220

GCD(3, 740) = ( 3 x 740 ) / 2220

= 3 / 740

= 3

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 621, 669, 740, 253 is 1
