Given numbers are 643, 290, 283, 483

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

Apply this formula for all numbers.

Step1:

LCM(643, 290) = 186470

GCD(643, 290) = ( 643 x 290 ) / 186470

= 643 / 290

= 643

Step2:

LCM(1, 283) = 283

GCD(1, 283) = ( 1 x 283 ) / 283

= 1 / 283

= 1

Step3:

LCM(1, 483) = 483

GCD(1, 483) = ( 1 x 483 ) / 483

= 1 / 483

= 1

So, Greatest Common Divisor of 643, 290, 283, 483 is 1
