Given numbers are 202, 430, 420, 881

The list of prime factors of all numbers are

Prime factors of 202 are 2 x 101

Prime factors of 430 are 2 x 5 x 43

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

Prime factors of 881 are 881

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

Given numbers are 202, 430, 420, 881

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

Apply this formula for all numbers.

Step1:

LCM(202, 430) = 43430

GCD(202, 430) = ( 202 x 430 ) / 43430

= 202 / 430

= 202

Step2:

LCM(2, 420) = 420

GCD(2, 420) = ( 2 x 420 ) / 420

= 2 / 420

= 2

Step3:

LCM(2, 881) = 1762

GCD(2, 881) = ( 2 x 881 ) / 1762

= 2 / 881

= 2

So, Greatest Common Divisor of 202, 430, 420, 881 is 1
