Given numbers are 573, 202, 66, 420

The list of prime factors of all numbers are

Prime factors of 573 are 3 x 191

Prime factors of 202 are 2 x 101

Prime factors of 66 are 2 x 3 x 11

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 573, 202, 66, 420

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

Apply this formula for all numbers.

Step1:

LCM(573, 202) = 115746

GCD(573, 202) = ( 573 x 202 ) / 115746

= 573 / 202

= 573

Step2:

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

= 1 / 66

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 573, 202, 66, 420 is 1
