Given numbers are 728, 247, 458, 869

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

Apply this formula for all numbers.

Step1:

LCM(728, 247) = 13832

GCD(728, 247) = ( 728 x 247 ) / 13832

= 728 / 247

= 728

Step2:

LCM(13, 458) = 5954

GCD(13, 458) = ( 13 x 458 ) / 5954

= 13 / 458

= 13

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 728, 247, 458, 869 is 1
