Given numbers are 889, 490, 235, 128

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

Apply this formula for all numbers.

Step1:

LCM(889, 490) = 62230

GCD(889, 490) = ( 889 x 490 ) / 62230

= 889 / 490

= 889

Step2:

LCM(7, 235) = 1645

GCD(7, 235) = ( 7 x 235 ) / 1645

= 7 / 235

= 7

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 889, 490, 235, 128 is 1
