Given numbers are 161, 840, 214, 123

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 214 are 2 x 107

Prime factors of 123 are 3 x 41

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

Given numbers are 161, 840, 214, 123

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

Apply this formula for all numbers.

Step1:

LCM(161, 840) = 19320

GCD(161, 840) = ( 161 x 840 ) / 19320

= 161 / 840

= 161

Step2:

LCM(7, 214) = 1498

GCD(7, 214) = ( 7 x 214 ) / 1498

= 7 / 214

= 7

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 161, 840, 214, 123 is 1
