Given numbers are 406, 197, 31, 166

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

Apply this formula for all numbers.

Step1:

LCM(406, 197) = 79982

GCD(406, 197) = ( 406 x 197 ) / 79982

= 406 / 197

= 406

Step2:

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

= 1 / 31

= 1

Step3:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

So, Greatest Common Divisor of 406, 197, 31, 166 is 1
