Given numbers are 602, 978, 222, 644

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

Apply this formula for all numbers.

Step1:

LCM(602, 978) = 294378

GCD(602, 978) = ( 602 x 978 ) / 294378

= 602 / 978

= 602

Step2:

LCM(2, 222) = 222

GCD(2, 222) = ( 2 x 222 ) / 222

= 2 / 222

= 2

Step3:

LCM(2, 644) = 644

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

= 2 / 644

= 2

So, Greatest Common Divisor of 602, 978, 222, 644 is 2
