Given numbers are 125, 346, 645, 120

The list of prime factors of all numbers are

Prime factors of 125 are 5 x 5 x 5

Prime factors of 346 are 2 x 173

Prime factors of 645 are 3 x 5 x 43

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 125, 346, 645, 120

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

Apply this formula for all numbers.

Step1:

LCM(125, 346) = 43250

GCD(125, 346) = ( 125 x 346 ) / 43250

= 125 / 346

= 125

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 120) = 120

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

= 1 / 120

= 1

So, Greatest Common Divisor of 125, 346, 645, 120 is 1
