Given numbers are 728, 655, 71, 899

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

Apply this formula for all numbers.

Step1:

LCM(728, 655) = 476840

GCD(728, 655) = ( 728 x 655 ) / 476840

= 728 / 655

= 728

Step2:

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

= 1 / 71

= 1

Step3:

LCM(1, 899) = 899

GCD(1, 899) = ( 1 x 899 ) / 899

= 1 / 899

= 1

So, Greatest Common Divisor of 728, 655, 71, 899 is 1
