Given numbers are 656, 469, 643, 347

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

Apply this formula for all numbers.

Step1:

LCM(656, 469) = 307664

GCD(656, 469) = ( 656 x 469 ) / 307664

= 656 / 469

= 656

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

So, Greatest Common Divisor of 656, 469, 643, 347 is 1
