Given numbers are 620, 100, 168, 386

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

Apply this formula for all numbers.

Step1:

LCM(620, 100) = 3100

GCD(620, 100) = ( 620 x 100 ) / 3100

= 620 / 100

= 620

Step2:

LCM(20, 168) = 840

GCD(20, 168) = ( 20 x 168 ) / 840

= 20 / 168

= 20

Step3:

LCM(4, 386) = 772

GCD(4, 386) = ( 4 x 386 ) / 772

= 4 / 386

= 4

So, Greatest Common Divisor of 620, 100, 168, 386 is 2
