Given numbers are 355, 923, 301, 640

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

Apply this formula for all numbers.

Step1:

LCM(355, 923) = 4615

GCD(355, 923) = ( 355 x 923 ) / 4615

= 355 / 923

= 355

Step2:

LCM(71, 301) = 21371

GCD(71, 301) = ( 71 x 301 ) / 21371

= 71 / 301

= 71

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 355, 923, 301, 640 is 1
