Given numbers are 671, 660, 629, 155

The list of prime factors of all numbers are

Prime factors of 671 are 11 x 61

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 629 are 17 x 37

Prime factors of 155 are 5 x 31

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

Given numbers are 671, 660, 629, 155

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

Apply this formula for all numbers.

Step1:

LCM(671, 660) = 40260

GCD(671, 660) = ( 671 x 660 ) / 40260

= 671 / 660

= 671

Step2:

LCM(11, 629) = 6919

GCD(11, 629) = ( 11 x 629 ) / 6919

= 11 / 629

= 11

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 671, 660, 629, 155 is 1
