Given numbers are 715, 574, 406, 621

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

Prime factors of 574 are 2 x 7 x 41

Prime factors of 406 are 2 x 7 x 29

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

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

Given numbers are 715, 574, 406, 621

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

Apply this formula for all numbers.

Step1:

LCM(715, 574) = 410410

GCD(715, 574) = ( 715 x 574 ) / 410410

= 715 / 574

= 715

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 715, 574, 406, 621 is 1
