Given numbers are 202, 357, 20, 354

The list of prime factors of all numbers are

Prime factors of 202 are 2 x 101

Prime factors of 357 are 3 x 7 x 17

Prime factors of 20 are 2 x 2 x 5

Prime factors of 354 are 2 x 3 x 59

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

Given numbers are 202, 357, 20, 354

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

Apply this formula for all numbers.

Step1:

LCM(202, 357) = 72114

GCD(202, 357) = ( 202 x 357 ) / 72114

= 202 / 357

= 202

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

Step3:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

So, Greatest Common Divisor of 202, 357, 20, 354 is 1
