Given numbers are 620, 808, 408, 178

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

Apply this formula for all numbers.

Step1:

LCM(620, 808) = 125240

GCD(620, 808) = ( 620 x 808 ) / 125240

= 620 / 808

= 620

Step2:

LCM(4, 408) = 408

GCD(4, 408) = ( 4 x 408 ) / 408

= 4 / 408

= 4

Step3:

LCM(4, 178) = 356

GCD(4, 178) = ( 4 x 178 ) / 356

= 4 / 178

= 4

So, Greatest Common Divisor of 620, 808, 408, 178 is 2
