Given numbers are 487, 643, 408, 222

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

Apply this formula for all numbers.

Step1:

LCM(487, 643) = 313141

GCD(487, 643) = ( 487 x 643 ) / 313141

= 487 / 643

= 487

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

So, Greatest Common Divisor of 487, 643, 408, 222 is 1
