Given numbers are 430, 561, 142, 346

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 561 are 3 x 11 x 17

Prime factors of 142 are 2 x 71

Prime factors of 346 are 2 x 173

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

Given numbers are 430, 561, 142, 346

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

Apply this formula for all numbers.

Step1:

LCM(430, 561) = 241230

GCD(430, 561) = ( 430 x 561 ) / 241230

= 430 / 561

= 430

Step2:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

Step3:

LCM(1, 346) = 346

GCD(1, 346) = ( 1 x 346 ) / 346

= 1 / 346

= 1

So, Greatest Common Divisor of 430, 561, 142, 346 is 1
