Given numbers are 202, 168, 617, 621

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

Apply this formula for all numbers.

Step1:

LCM(202, 168) = 16968

GCD(202, 168) = ( 202 x 168 ) / 16968

= 202 / 168

= 202

Step2:

LCM(2, 617) = 1234

GCD(2, 617) = ( 2 x 617 ) / 1234

= 2 / 617

= 2

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 202, 168, 617, 621 is 1
