Given numbers are 142, 145, 164, 556

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 145 are 5 x 29

Prime factors of 164 are 2 x 2 x 41

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 142, 145, 164, 556

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

Apply this formula for all numbers.

Step1:

LCM(142, 145) = 20590

GCD(142, 145) = ( 142 x 145 ) / 20590

= 142 / 145

= 142

Step2:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 142, 145, 164, 556 is 1
