Given numbers are 388, 720, 217, 696

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

Apply this formula for all numbers.

Step1:

LCM(388, 720) = 69840

GCD(388, 720) = ( 388 x 720 ) / 69840

= 388 / 720

= 388

Step2:

LCM(4, 217) = 868

GCD(4, 217) = ( 4 x 217 ) / 868

= 4 / 217

= 4

Step3:

LCM(1, 696) = 696

GCD(1, 696) = ( 1 x 696 ) / 696

= 1 / 696

= 1

So, Greatest Common Divisor of 388, 720, 217, 696 is 1
