The list of prime factors of all numbers are

Prime factors of 958 are 2 x 479

Prime factors of 221 are 13 x 17

Prime factors of 580 are 2 x 2 x 5 x 29

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 958, 221, 580, 840

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

Apply this formula for all numbers.

Step1:

LCM(958, 221) = 211718

GCD(958, 221) = ( 958 x 221 ) / 211718

= 958 / 221

= 958

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 958, 221, 580, 840 is 1
