Given numbers are 388, 616, 155, 115

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

Apply this formula for all numbers.

Step1:

LCM(388, 616) = 59752

GCD(388, 616) = ( 388 x 616 ) / 59752

= 388 / 616

= 388

Step2:

LCM(4, 155) = 620

GCD(4, 155) = ( 4 x 155 ) / 620

= 4 / 155

= 4

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 388, 616, 155, 115 is 1
