Given numbers are 658, 154, 366, 408

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

Apply this formula for all numbers.

Step1:

LCM(658, 154) = 7238

GCD(658, 154) = ( 658 x 154 ) / 7238

= 658 / 154

= 658

Step2:

LCM(14, 366) = 2562

GCD(14, 366) = ( 14 x 366 ) / 2562

= 14 / 366

= 14

Step3:

LCM(2, 408) = 408

GCD(2, 408) = ( 2 x 408 ) / 408

= 2 / 408

= 2

So, Greatest Common Divisor of 658, 154, 366, 408 is 2
