Given numbers are 658, 322, 173, 138

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

Apply this formula for all numbers.

Step1:

LCM(658, 322) = 15134

GCD(658, 322) = ( 658 x 322 ) / 15134

= 658 / 322

= 658

Step2:

LCM(14, 173) = 2422

GCD(14, 173) = ( 14 x 173 ) / 2422

= 14 / 173

= 14

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 658, 322, 173, 138 is 1
