Given numbers are 628, 622, 715, 423

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

Prime factors of 622 are 2 x 311

Prime factors of 715 are 5 x 11 x 13

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 628, 622, 715, 423

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

Apply this formula for all numbers.

Step1:

LCM(628, 622) = 195308

GCD(628, 622) = ( 628 x 622 ) / 195308

= 628 / 622

= 628

Step2:

LCM(2, 715) = 1430

GCD(2, 715) = ( 2 x 715 ) / 1430

= 2 / 715

= 2

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 628, 622, 715, 423 is 1
