Given numbers are 858, 693, 800, 643

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

Apply this formula for all numbers.

Step1:

LCM(858, 693) = 18018

GCD(858, 693) = ( 858 x 693 ) / 18018

= 858 / 693

= 858

Step2:

LCM(33, 800) = 26400

GCD(33, 800) = ( 33 x 800 ) / 26400

= 33 / 800

= 33

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 858, 693, 800, 643 is 1
