Given numbers are 128, 147, 789, 894

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

Apply this formula for all numbers.

Step1:

LCM(128, 147) = 18816

GCD(128, 147) = ( 128 x 147 ) / 18816

= 128 / 147

= 128

Step2:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

Step3:

LCM(1, 894) = 894

GCD(1, 894) = ( 1 x 894 ) / 894

= 1 / 894

= 1

So, Greatest Common Divisor of 128, 147, 789, 894 is 1
