Given numbers are 871, 128, 935, 643

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

Apply this formula for all numbers.

Step1:

LCM(871, 128) = 111488

GCD(871, 128) = ( 871 x 128 ) / 111488

= 871 / 128

= 871

Step2:

LCM(1, 935) = 935

GCD(1, 935) = ( 1 x 935 ) / 935

= 1 / 935

= 1

Step3:

LCM(1, 643) = 643

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

= 1 / 643

= 1

So, Greatest Common Divisor of 871, 128, 935, 643 is 1
