Given numbers are 728, 153, 553

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

Apply this formula for all numbers.

Step1:

LCM(728, 153) = 111384

GCD(728, 153) = ( 728 x 153 ) / 111384

= 728 / 153

= 728

Step2:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 728, 153, 553 is 1
