Given numbers are 655, 460, 577, 643

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

Apply this formula for all numbers.

Step1:

LCM(655, 460) = 60260

GCD(655, 460) = ( 655 x 460 ) / 60260

= 655 / 460

= 655

Step2:

LCM(5, 577) = 2885

GCD(5, 577) = ( 5 x 577 ) / 2885

= 5 / 577

= 5

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 655, 460, 577, 643 is 1
