Given numbers are 642, 311, 883, 556

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

Apply this formula for all numbers.

Step1:

LCM(642, 311) = 199662

GCD(642, 311) = ( 642 x 311 ) / 199662

= 642 / 311

= 642

Step2:

LCM(1, 883) = 883

GCD(1, 883) = ( 1 x 883 ) / 883

= 1 / 883

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 642, 311, 883, 556 is 1
