Given numbers are 550, 889, 20

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

Apply this formula for all numbers.

Step1:

LCM(550, 889) = 488950

GCD(550, 889) = ( 550 x 889 ) / 488950

= 550 / 889

= 550

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

So, Greatest Common Divisor of 550, 889, 20 is 1
