Given numbers are 728, 343, 579, 178

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

Apply this formula for all numbers.

Step1:

LCM(728, 343) = 35672

GCD(728, 343) = ( 728 x 343 ) / 35672

= 728 / 343

= 728

Step2:

LCM(7, 579) = 4053

GCD(7, 579) = ( 7 x 579 ) / 4053

= 7 / 579

= 7

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 728, 343, 579, 178 is 1
