Given numbers are 643, 697, 230, 288

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

Apply this formula for all numbers.

Step1:

LCM(643, 697) = 448171

GCD(643, 697) = ( 643 x 697 ) / 448171

= 643 / 697

= 643

Step2:

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

= 1 / 230

= 1

Step3:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

So, Greatest Common Divisor of 643, 697, 230, 288 is 1
