Given numbers are 128, 871, 857, 887

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

Apply this formula for all numbers.

Step1:

LCM(128, 871) = 111488

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

= 128 / 871

= 128

Step2:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

Step3:

LCM(1, 887) = 887

GCD(1, 887) = ( 1 x 887 ) / 887

= 1 / 887

= 1

So, Greatest Common Divisor of 128, 871, 857, 887 is 1
