Given numbers are 470, 555, 391

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

Apply this formula for all numbers.

Step1:

LCM(470, 555) = 52170

GCD(470, 555) = ( 470 x 555 ) / 52170

= 470 / 555

= 470

Step2:

LCM(5, 391) = 1955

GCD(5, 391) = ( 5 x 391 ) / 1955

= 5 / 391

= 5

So, Greatest Common Divisor of 470, 555, 391 is 1
