Given numbers are 656, 340, 585, 164

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

Apply this formula for all numbers.

Step1:

LCM(656, 340) = 55760

GCD(656, 340) = ( 656 x 340 ) / 55760

= 656 / 340

= 656

Step2:

LCM(4, 585) = 2340

GCD(4, 585) = ( 4 x 585 ) / 2340

= 4 / 585

= 4

Step3:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

So, Greatest Common Divisor of 656, 340, 585, 164 is 1
