Given numbers are 645, 917, 439, 113

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

Apply this formula for all numbers.

Step1:

LCM(645, 917) = 591465

GCD(645, 917) = ( 645 x 917 ) / 591465

= 645 / 917

= 645

Step2:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

Step3:

LCM(1, 113) = 113

GCD(1, 113) = ( 1 x 113 ) / 113

= 1 / 113

= 1

So, Greatest Common Divisor of 645, 917, 439, 113 is 1
