Given numbers are 643, 916, 318, 259

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

Apply this formula for all numbers.

Step1:

LCM(643, 916) = 588988

GCD(643, 916) = ( 643 x 916 ) / 588988

= 643 / 916

= 643

Step2:

LCM(1, 318) = 318

GCD(1, 318) = ( 1 x 318 ) / 318

= 1 / 318

= 1

Step3:

LCM(1, 259) = 259

GCD(1, 259) = ( 1 x 259 ) / 259

= 1 / 259

= 1

So, Greatest Common Divisor of 643, 916, 318, 259 is 1
