Given numbers are 728, 724, 786, 258

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

Apply this formula for all numbers.

Step1:

LCM(728, 724) = 131768

GCD(728, 724) = ( 728 x 724 ) / 131768

= 728 / 724

= 728

Step2:

LCM(4, 786) = 1572

GCD(4, 786) = ( 4 x 786 ) / 1572

= 4 / 786

= 4

Step3:

LCM(2, 258) = 258

GCD(2, 258) = ( 2 x 258 ) / 258

= 2 / 258

= 2

So, Greatest Common Divisor of 728, 724, 786, 258 is 2
