Given numbers are 989, 166, 861, 946

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

Apply this formula for all numbers.

Step1:

LCM(989, 166) = 164174

GCD(989, 166) = ( 989 x 166 ) / 164174

= 989 / 166

= 989

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 946) = 946

GCD(1, 946) = ( 1 x 946 ) / 946

= 1 / 946

= 1

So, Greatest Common Divisor of 989, 166, 861, 946 is 1
