Given numbers are 840, 324, 698, 979

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 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 698 are 2 x 349

Prime factors of 979 are 11 x 89

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

Given numbers are 840, 324, 698, 979

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

Apply this formula for all numbers.

Step1:

LCM(840, 324) = 22680

GCD(840, 324) = ( 840 x 324 ) / 22680

= 840 / 324

= 840

Step2:

LCM(12, 698) = 4188

GCD(12, 698) = ( 12 x 698 ) / 4188

= 12 / 698

= 12

Step3:

LCM(2, 979) = 1958

GCD(2, 979) = ( 2 x 979 ) / 1958

= 2 / 979

= 2

So, Greatest Common Divisor of 840, 324, 698, 979 is 1
