Given numbers are 557, 501, 455, 728

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

Apply this formula for all numbers.

Step1:

LCM(557, 501) = 279057

GCD(557, 501) = ( 557 x 501 ) / 279057

= 557 / 501

= 557

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 728) = 728

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

= 1 / 728

= 1

So, Greatest Common Divisor of 557, 501, 455, 728 is 1
