Given numbers are 856, 512, 345, 643

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

Apply this formula for all numbers.

Step1:

LCM(856, 512) = 54784

GCD(856, 512) = ( 856 x 512 ) / 54784

= 856 / 512

= 856

Step2:

LCM(8, 345) = 2760

GCD(8, 345) = ( 8 x 345 ) / 2760

= 8 / 345

= 8

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 856, 512, 345, 643 is 1
