Given numbers are 506, 222, 557, 643

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

Apply this formula for all numbers.

Step1:

LCM(506, 222) = 56166

GCD(506, 222) = ( 506 x 222 ) / 56166

= 506 / 222

= 506

Step2:

LCM(2, 557) = 1114

GCD(2, 557) = ( 2 x 557 ) / 1114

= 2 / 557

= 2

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 506, 222, 557, 643 is 1
