Given numbers are 196, 168, 428, 197

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

Apply this formula for all numbers.

Step1:

LCM(196, 168) = 1176

GCD(196, 168) = ( 196 x 168 ) / 1176

= 196 / 168

= 196

Step2:

LCM(28, 428) = 2996

GCD(28, 428) = ( 28 x 428 ) / 2996

= 28 / 428

= 28

Step3:

LCM(4, 197) = 788

GCD(4, 197) = ( 4 x 197 ) / 788

= 4 / 197

= 4

So, Greatest Common Divisor of 196, 168, 428, 197 is 1
