Given numbers are 322, 665, 830, 840

The list of prime factors of all numbers are

Prime factors of 322 are 2 x 7 x 23

Prime factors of 665 are 5 x 7 x 19

Prime factors of 830 are 2 x 5 x 83

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

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

Given numbers are 322, 665, 830, 840

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

Apply this formula for all numbers.

Step1:

LCM(322, 665) = 30590

GCD(322, 665) = ( 322 x 665 ) / 30590

= 322 / 665

= 322

Step2:

LCM(7, 830) = 5810

GCD(7, 830) = ( 7 x 830 ) / 5810

= 7 / 830

= 7

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 322, 665, 830, 840 is 1
