Given numbers are 102, 815, 688, 388

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

Apply this formula for all numbers.

Step1:

LCM(102, 815) = 83130

GCD(102, 815) = ( 102 x 815 ) / 83130

= 102 / 815

= 102

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 102, 815, 688, 388 is 1
