Given numbers are 163, 145, 140, 120

The list of prime factors of all numbers are

Prime factors of 163 are 163

Prime factors of 145 are 5 x 29

Prime factors of 140 are 2 x 2 x 5 x 7

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 163, 145, 140, 120

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

Apply this formula for all numbers.

Step1:

LCM(163, 145) = 23635

GCD(163, 145) = ( 163 x 145 ) / 23635

= 163 / 145

= 163

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

Step3:

LCM(1, 120) = 120

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

= 1 / 120

= 1

So, Greatest Common Divisor of 163, 145, 140, 120 is 1
