Given numbers are 435, 656, 54, 721

The list of prime factors of all numbers are

Prime factors of 435 are 3 x 5 x 29

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 54 are 2 x 3 x 3 x 3

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 435, 656, 54, 721

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

Apply this formula for all numbers.

Step1:

LCM(435, 656) = 285360

GCD(435, 656) = ( 435 x 656 ) / 285360

= 435 / 656

= 435

Step2:

LCM(1, 54) = 54

GCD(1, 54) = ( 1 x 54 ) / 54

= 1 / 54

= 1

Step3:

LCM(1, 721) = 721

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

= 1 / 721

= 1

So, Greatest Common Divisor of 435, 656, 54, 721 is 1
