Given numbers are 550, 556, 650, 810

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

Apply this formula for all numbers.

Step1:

LCM(550, 556) = 152900

GCD(550, 556) = ( 550 x 556 ) / 152900

= 550 / 556

= 550

Step2:

LCM(2, 650) = 650

GCD(2, 650) = ( 2 x 650 ) / 650

= 2 / 650

= 2

Step3:

LCM(2, 810) = 810

GCD(2, 810) = ( 2 x 810 ) / 810

= 2 / 810

= 2

So, Greatest Common Divisor of 550, 556, 650, 810 is 2
