Given numbers are 891, 242, 538, 256

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

Apply this formula for all numbers.

Step1:

LCM(891, 242) = 19602

GCD(891, 242) = ( 891 x 242 ) / 19602

= 891 / 242

= 891

Step2:

LCM(11, 538) = 5918

GCD(11, 538) = ( 11 x 538 ) / 5918

= 11 / 538

= 11

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 891, 242, 538, 256 is 1
