Given numbers are 621, 253, 531, 802

The list of prime factors of all numbers are

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

Prime factors of 253 are 11 x 23

Prime factors of 531 are 3 x 3 x 59

Prime factors of 802 are 2 x 401

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

Given numbers are 621, 253, 531, 802

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

Apply this formula for all numbers.

Step1:

LCM(621, 253) = 6831

GCD(621, 253) = ( 621 x 253 ) / 6831

= 621 / 253

= 621

Step2:

LCM(23, 531) = 12213

GCD(23, 531) = ( 23 x 531 ) / 12213

= 23 / 531

= 23

Step3:

LCM(1, 802) = 802

GCD(1, 802) = ( 1 x 802 ) / 802

= 1 / 802

= 1

So, Greatest Common Divisor of 621, 253, 531, 802 is 1
