Given numbers are 381, 738, 124, 688

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

Apply this formula for all numbers.

Step1:

LCM(381, 738) = 93726

GCD(381, 738) = ( 381 x 738 ) / 93726

= 381 / 738

= 381

Step2:

LCM(3, 124) = 372

GCD(3, 124) = ( 3 x 124 ) / 372

= 3 / 124

= 3

Step3:

LCM(1, 688) = 688

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

= 1 / 688

= 1

So, Greatest Common Divisor of 381, 738, 124, 688 is 1
