The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 172 are 2 x 2 x 43

Prime factors of 746 are 2 x 373

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

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

Given numbers are 845, 172, 746, 120

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

Apply this formula for all numbers.

Step1:

LCM(845, 172) = 145340

GCD(845, 172) = ( 845 x 172 ) / 145340

= 845 / 172

= 845

Step2:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

Step3:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

So, Greatest Common Divisor of 845, 172, 746, 120 is 1
