Given numbers are 256, 476, 747, 221

The list of prime factors of all numbers are

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 747 are 3 x 3 x 83

Prime factors of 221 are 13 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 256, 476, 747, 221

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

Apply this formula for all numbers.

Step1:

LCM(256, 476) = 30464

GCD(256, 476) = ( 256 x 476 ) / 30464

= 256 / 476

= 256

Step2:

LCM(4, 747) = 2988

GCD(4, 747) = ( 4 x 747 ) / 2988

= 4 / 747

= 4

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 256, 476, 747, 221 is 1
