Given numbers are 166, 438, 297, 658

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

Apply this formula for all numbers.

Step1:

LCM(166, 438) = 36354

GCD(166, 438) = ( 166 x 438 ) / 36354

= 166 / 438

= 166

Step2:

LCM(2, 297) = 594

GCD(2, 297) = ( 2 x 297 ) / 594

= 2 / 297

= 2

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 166, 438, 297, 658 is 1
