Given numbers are 128, 870, 283, 997

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

Apply this formula for all numbers.

Step1:

LCM(128, 870) = 55680

GCD(128, 870) = ( 128 x 870 ) / 55680

= 128 / 870

= 128

Step2:

LCM(2, 283) = 566

GCD(2, 283) = ( 2 x 283 ) / 566

= 2 / 283

= 2

Step3:

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

= 1 / 997

= 1

So, Greatest Common Divisor of 128, 870, 283, 997 is 1
