Given numbers are 921, 166, 664, 985

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

Apply this formula for all numbers.

Step1:

LCM(921, 166) = 152886

GCD(921, 166) = ( 921 x 166 ) / 152886

= 921 / 166

= 921

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

So, Greatest Common Divisor of 921, 166, 664, 985 is 1
