The list of prime factors of all numbers are

Prime factors of 942 are 2 x 3 x 157

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 689 are 13 x 53

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

Given numbers are 942, 770, 720, 689

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

Apply this formula for all numbers.

Step1:

LCM(942, 770) = 362670

GCD(942, 770) = ( 942 x 770 ) / 362670

= 942 / 770

= 942

Step2:

LCM(2, 720) = 720

GCD(2, 720) = ( 2 x 720 ) / 720

= 2 / 720

= 2

Step3:

LCM(2, 689) = 1378

GCD(2, 689) = ( 2 x 689 ) / 1378

= 2 / 689

= 2

So, Greatest Common Divisor of 942, 770, 720, 689 is 1
