Given numbers are 658, 238, 343, 671

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

Apply this formula for all numbers.

Step1:

LCM(658, 238) = 11186

GCD(658, 238) = ( 658 x 238 ) / 11186

= 658 / 238

= 658

Step2:

LCM(14, 343) = 686

GCD(14, 343) = ( 14 x 343 ) / 686

= 14 / 343

= 14

Step3:

LCM(7, 671) = 4697

GCD(7, 671) = ( 7 x 671 ) / 4697

= 7 / 671

= 7

So, Greatest Common Divisor of 658, 238, 343, 671 is 1
