Given numbers are 329, 408, 840, 159

The list of prime factors of all numbers are

Prime factors of 329 are 7 x 47

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Prime factors of 159 are 3 x 53

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

Given numbers are 329, 408, 840, 159

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

Apply this formula for all numbers.

Step1:

LCM(329, 408) = 134232

GCD(329, 408) = ( 329 x 408 ) / 134232

= 329 / 408

= 329

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 329, 408, 840, 159 is 1
