Given numbers are 193, 668, 886, 420

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

Apply this formula for all numbers.

Step1:

LCM(193, 668) = 128924

GCD(193, 668) = ( 193 x 668 ) / 128924

= 193 / 668

= 193

Step2:

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

= 1 / 886

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 193, 668, 886, 420 is 1
