Given numbers are 218, 475, 645

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

Apply this formula for all numbers.

Step1:

LCM(218, 475) = 103550

GCD(218, 475) = ( 218 x 475 ) / 103550

= 218 / 475

= 218

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 218, 475, 645 is 1
