Given numbers are 436, 250, 455, 721

The list of prime factors of all numbers are

Prime factors of 436 are 2 x 2 x 109

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 455 are 5 x 7 x 13

Prime factors of 721 are 7 x 103

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

Given numbers are 436, 250, 455, 721

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

Apply this formula for all numbers.

Step1:

LCM(436, 250) = 54500

GCD(436, 250) = ( 436 x 250 ) / 54500

= 436 / 250

= 436

Step2:

LCM(2, 455) = 910

GCD(2, 455) = ( 2 x 455 ) / 910

= 2 / 455

= 2

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 436, 250, 455, 721 is 1
