Given numbers are 646, 636, 128, 544

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

Apply this formula for all numbers.

Step1:

LCM(646, 636) = 205428

GCD(646, 636) = ( 646 x 636 ) / 205428

= 646 / 636

= 646

Step2:

LCM(2, 128) = 128

GCD(2, 128) = ( 2 x 128 ) / 128

= 2 / 128

= 2

Step3:

LCM(2, 544) = 544

GCD(2, 544) = ( 2 x 544 ) / 544

= 2 / 544

= 2

So, Greatest Common Divisor of 646, 636, 128, 544 is 2
