Given numbers are 620, 820, 550

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

Apply this formula for all numbers.

Step1:

LCM(620, 820) = 25420

GCD(620, 820) = ( 620 x 820 ) / 25420

= 620 / 820

= 620

Step2:

LCM(20, 550) = 1100

GCD(20, 550) = ( 20 x 550 ) / 1100

= 20 / 550

= 20

So, Greatest Common Divisor of 620, 820, 550 is 10
