Given numbers are 387, 238, 561, 794

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

Apply this formula for all numbers.

Step1:

LCM(387, 238) = 92106

GCD(387, 238) = ( 387 x 238 ) / 92106

= 387 / 238

= 387

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 794) = 794

GCD(1, 794) = ( 1 x 794 ) / 794

= 1 / 794

= 1

So, Greatest Common Divisor of 387, 238, 561, 794 is 1
