Given numbers are 196, 668, 85, 171

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

Apply this formula for all numbers.

Step1:

LCM(196, 668) = 32732

GCD(196, 668) = ( 196 x 668 ) / 32732

= 196 / 668

= 196

Step2:

LCM(4, 85) = 340

GCD(4, 85) = ( 4 x 85 ) / 340

= 4 / 85

= 4

Step3:

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

= 1 / 171

= 1

So, Greatest Common Divisor of 196, 668, 85, 171 is 1
