Given numbers are 645, 797, 195

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

Apply this formula for all numbers.

Step1:

LCM(645, 797) = 514065

GCD(645, 797) = ( 645 x 797 ) / 514065

= 645 / 797

= 645

Step2:

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

= 1 / 195

= 1

So, Greatest Common Divisor of 645, 797, 195 is 1
