Given numbers are 646, 169, 205, 622

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

Apply this formula for all numbers.

Step1:

LCM(646, 169) = 109174

GCD(646, 169) = ( 646 x 169 ) / 109174

= 646 / 169

= 646

Step2:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

Step3:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

So, Greatest Common Divisor of 646, 169, 205, 622 is 1
