Given numbers are 989, 168, 620, 611

The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 611 are 13 x 47

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

Given numbers are 989, 168, 620, 611

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

Apply this formula for all numbers.

Step1:

LCM(989, 168) = 166152

GCD(989, 168) = ( 989 x 168 ) / 166152

= 989 / 168

= 989

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 989, 168, 620, 611 is 1
