Given numbers are 873, 153, 168, 421

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

Apply this formula for all numbers.

Step1:

LCM(873, 153) = 14841

GCD(873, 153) = ( 873 x 153 ) / 14841

= 873 / 153

= 873

Step2:

LCM(9, 168) = 504

GCD(9, 168) = ( 9 x 168 ) / 504

= 9 / 168

= 9

Step3:

LCM(3, 421) = 1263

GCD(3, 421) = ( 3 x 421 ) / 1263

= 3 / 421

= 3

So, Greatest Common Divisor of 873, 153, 168, 421 is 1
