Given numbers are 679, 422, 840, 330

The list of prime factors of all numbers are

Prime factors of 679 are 7 x 97

Prime factors of 422 are 2 x 211

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

Prime factors of 330 are 2 x 3 x 5 x 11

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

Given numbers are 679, 422, 840, 330

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

Apply this formula for all numbers.

Step1:

LCM(679, 422) = 286538

GCD(679, 422) = ( 679 x 422 ) / 286538

= 679 / 422

= 679

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

So, Greatest Common Divisor of 679, 422, 840, 330 is 1
