Given numbers are 621, 230, 812, 169

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

Apply this formula for all numbers.

Step1:

LCM(621, 230) = 6210

GCD(621, 230) = ( 621 x 230 ) / 6210

= 621 / 230

= 621

Step2:

LCM(23, 812) = 18676

GCD(23, 812) = ( 23 x 812 ) / 18676

= 23 / 812

= 23

Step3:

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

= 1 / 169

= 1

So, Greatest Common Divisor of 621, 230, 812, 169 is 1
