Given numbers are 174, 620, 644, 812

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

Apply this formula for all numbers.

Step1:

LCM(174, 620) = 53940

GCD(174, 620) = ( 174 x 620 ) / 53940

= 174 / 620

= 174

Step2:

LCM(2, 644) = 644

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

= 2 / 644

= 2

Step3:

LCM(2, 812) = 812

GCD(2, 812) = ( 2 x 812 ) / 812

= 2 / 812

= 2

So, Greatest Common Divisor of 174, 620, 644, 812 is 2
