Given numbers are 215, 989, 689, 804

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

Apply this formula for all numbers.

Step1:

LCM(215, 989) = 4945

GCD(215, 989) = ( 215 x 989 ) / 4945

= 215 / 989

= 215

Step2:

LCM(43, 689) = 29627

GCD(43, 689) = ( 43 x 689 ) / 29627

= 43 / 689

= 43

Step3:

LCM(1, 804) = 804

GCD(1, 804) = ( 1 x 804 ) / 804

= 1 / 804

= 1

So, Greatest Common Divisor of 215, 989, 689, 804 is 1
