Given numbers are 840, 332, 79, 165

The list of prime factors of all numbers are

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

Prime factors of 332 are 2 x 2 x 83

Prime factors of 79 are 79

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 840, 332, 79, 165

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

Apply this formula for all numbers.

Step1:

LCM(840, 332) = 69720

GCD(840, 332) = ( 840 x 332 ) / 69720

= 840 / 332

= 840

Step2:

LCM(4, 79) = 316

GCD(4, 79) = ( 4 x 79 ) / 316

= 4 / 79

= 4

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 840, 332, 79, 165 is 1
