Given numbers are 254, 821, 128

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

Apply this formula for all numbers.

Step1:

LCM(254, 821) = 208534

GCD(254, 821) = ( 254 x 821 ) / 208534

= 254 / 821

= 254

Step2:

LCM(1, 128) = 128

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

= 1 / 128

= 1

So, Greatest Common Divisor of 254, 821, 128 is 1
