Given numbers are 558, 646, 646, 683

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

Apply this formula for all numbers.

Step1:

LCM(558, 646) = 180234

GCD(558, 646) = ( 558 x 646 ) / 180234

= 558 / 646

= 558

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 683) = 1366

GCD(2, 683) = ( 2 x 683 ) / 1366

= 2 / 683

= 2

So, Greatest Common Divisor of 558, 646, 646, 683 is 1
