Given numbers are 421, 200, 540, 397

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 397 are 397

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

Given numbers are 421, 200, 540, 397

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

Apply this formula for all numbers.

Step1:

LCM(421, 200) = 84200

GCD(421, 200) = ( 421 x 200 ) / 84200

= 421 / 200

= 421

Step2:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 421, 200, 540, 397 is 1
