Given numbers are 487, 407, 879, 728

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

Apply this formula for all numbers.

Step1:

LCM(487, 407) = 198209

GCD(487, 407) = ( 487 x 407 ) / 198209

= 487 / 407

= 487

Step2:

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

= 1 / 879

= 1

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 487, 407, 879, 728 is 1
