Given numbers are 189, 469, 163, 721

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

Apply this formula for all numbers.

Step1:

LCM(189, 469) = 12663

GCD(189, 469) = ( 189 x 469 ) / 12663

= 189 / 469

= 189

Step2:

LCM(7, 163) = 1141

GCD(7, 163) = ( 7 x 163 ) / 1141

= 7 / 163

= 7

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 189, 469, 163, 721 is 1
