Given numbers are 645, 479, 833, 289

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

Apply this formula for all numbers.

Step1:

LCM(645, 479) = 308955

GCD(645, 479) = ( 645 x 479 ) / 308955

= 645 / 479

= 645

Step2:

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

= 1 / 833

= 1

Step3:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

So, Greatest Common Divisor of 645, 479, 833, 289 is 1
