Given numbers are 328, 668, 840, 424

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

Apply this formula for all numbers.

Step1:

LCM(328, 668) = 54776

GCD(328, 668) = ( 328 x 668 ) / 54776

= 328 / 668

= 328

Step2:

LCM(4, 840) = 840

GCD(4, 840) = ( 4 x 840 ) / 840

= 4 / 840

= 4

Step3:

LCM(4, 424) = 424

GCD(4, 424) = ( 4 x 424 ) / 424

= 4 / 424

= 4

So, Greatest Common Divisor of 328, 668, 840, 424 is 4
