Given numbers are 141, 205, 104, 420

The list of prime factors of all numbers are

Prime factors of 141 are 3 x 47

Prime factors of 205 are 5 x 41

Prime factors of 104 are 2 x 2 x 2 x 13

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 141, 205, 104, 420

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

Apply this formula for all numbers.

Step1:

LCM(141, 205) = 28905

GCD(141, 205) = ( 141 x 205 ) / 28905

= 141 / 205

= 141

Step2:

LCM(1, 104) = 104

GCD(1, 104) = ( 1 x 104 ) / 104

= 1 / 104

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 141, 205, 104, 420 is 1
