The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 645 are 3 x 5 x 43

Prime factors of 646 are 2 x 17 x 19

Prime factors of 586 are 2 x 293

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

Given numbers are 155, 645, 646, 586

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

Apply this formula for all numbers.

Step1:

LCM(155, 645) = 19995

GCD(155, 645) = ( 155 x 645 ) / 19995

= 155 / 645

= 155

Step2:

LCM(5, 646) = 3230

GCD(5, 646) = ( 5 x 646 ) / 3230

= 5 / 646

= 5

Step3:

LCM(1, 586) = 586

GCD(1, 586) = ( 1 x 586 ) / 586

= 1 / 586

= 1

So, Greatest Common Divisor of 155, 645, 646, 586 is 1
