Given numbers are 810, 646, 644, 622

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

Apply this formula for all numbers.

Step1:

LCM(810, 646) = 261630

GCD(810, 646) = ( 810 x 646 ) / 261630

= 810 / 646

= 810

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 622) = 622

GCD(2, 622) = ( 2 x 622 ) / 622

= 2 / 622

= 2

So, Greatest Common Divisor of 810, 646, 644, 622 is 2
