Given numbers are 427, 820, 555

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

Apply this formula for all numbers.

Step1:

LCM(427, 820) = 350140

GCD(427, 820) = ( 427 x 820 ) / 350140

= 427 / 820

= 427

Step2:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 427, 820, 555 is 1
