The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 371 are 7 x 53

Prime factors of 356 are 2 x 2 x 89

Prime factors of 146 are 2 x 73

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

Given numbers are 561, 371, 356, 146

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

Apply this formula for all numbers.

Step1:

LCM(561, 371) = 208131

GCD(561, 371) = ( 561 x 371 ) / 208131

= 561 / 371

= 561

Step2:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

Step3:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

So, Greatest Common Divisor of 561, 371, 356, 146 is 1
