Given numbers are 128, 610, 891, 538

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

Apply this formula for all numbers.

Step1:

LCM(128, 610) = 39040

GCD(128, 610) = ( 128 x 610 ) / 39040

= 128 / 610

= 128

Step2:

LCM(2, 891) = 1782

GCD(2, 891) = ( 2 x 891 ) / 1782

= 2 / 891

= 2

Step3:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

So, Greatest Common Divisor of 128, 610, 891, 538 is 1
