Given numbers are 643, 873, 986, 573

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

Apply this formula for all numbers.

Step1:

LCM(643, 873) = 561339

GCD(643, 873) = ( 643 x 873 ) / 561339

= 643 / 873

= 643

Step2:

LCM(1, 986) = 986

GCD(1, 986) = ( 1 x 986 ) / 986

= 1 / 986

= 1

Step3:

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

= 1 / 573

= 1

So, Greatest Common Divisor of 643, 873, 986, 573 is 1
