Given numbers are 989, 521, 418, 840

The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

Prime factors of 521 are 521

Prime factors of 418 are 2 x 11 x 19

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 989, 521, 418, 840

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

Apply this formula for all numbers.

Step1:

LCM(989, 521) = 515269

GCD(989, 521) = ( 989 x 521 ) / 515269

= 989 / 521

= 989

Step2:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 989, 521, 418, 840 is 1
