Given numbers are 168, 189, 921, 260

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

Apply this formula for all numbers.

Step1:

LCM(168, 189) = 1512

GCD(168, 189) = ( 168 x 189 ) / 1512

= 168 / 189

= 168

Step2:

LCM(21, 921) = 6447

GCD(21, 921) = ( 21 x 921 ) / 6447

= 21 / 921

= 21

Step3:

LCM(3, 260) = 780

GCD(3, 260) = ( 3 x 260 ) / 780

= 3 / 260

= 3

So, Greatest Common Divisor of 168, 189, 921, 260 is 1
