Given numbers are 556, 123, 527, 455

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

Apply this formula for all numbers.

Step1:

LCM(556, 123) = 68388

GCD(556, 123) = ( 556 x 123 ) / 68388

= 556 / 123

= 556

Step2:

LCM(1, 527) = 527

GCD(1, 527) = ( 1 x 527 ) / 527

= 1 / 527

= 1

Step3:

LCM(1, 455) = 455

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

= 1 / 455

= 1

So, Greatest Common Divisor of 556, 123, 527, 455 is 1
