Given numbers are 646, 608, 558, 444

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

Apply this formula for all numbers.

Step1:

LCM(646, 608) = 10336

GCD(646, 608) = ( 646 x 608 ) / 10336

= 646 / 608

= 646

Step2:

LCM(38, 558) = 10602

GCD(38, 558) = ( 38 x 558 ) / 10602

= 38 / 558

= 38

Step3:

LCM(2, 444) = 444

GCD(2, 444) = ( 2 x 444 ) / 444

= 2 / 444

= 2

So, Greatest Common Divisor of 646, 608, 558, 444 is 2
