The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 554 are 2 x 277

Prime factors of 343 are 7 x 7 x 7

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

Given numbers are 989, 156, 554, 343

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

Apply this formula for all numbers.

Step1:

LCM(989, 156) = 154284

GCD(989, 156) = ( 989 x 156 ) / 154284

= 989 / 156

= 989

Step2:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

Step3:

LCM(1, 343) = 343

GCD(1, 343) = ( 1 x 343 ) / 343

= 1 / 343

= 1

So, Greatest Common Divisor of 989, 156, 554, 343 is 1
