Given numbers are 812, 620, 396, 572

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

Apply this formula for all numbers.

Step1:

LCM(812, 620) = 125860

GCD(812, 620) = ( 812 x 620 ) / 125860

= 812 / 620

= 812

Step2:

LCM(4, 396) = 396

GCD(4, 396) = ( 4 x 396 ) / 396

= 4 / 396

= 4

Step3:

LCM(4, 572) = 572

GCD(4, 572) = ( 4 x 572 ) / 572

= 4 / 572

= 4

So, Greatest Common Divisor of 812, 620, 396, 572 is 4
