Given numbers are 728, 421, 423, 786

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

Apply this formula for all numbers.

Step1:

LCM(728, 421) = 306488

GCD(728, 421) = ( 728 x 421 ) / 306488

= 728 / 421

= 728

Step2:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 728, 421, 423, 786 is 1
