Given numbers are 221, 851, 400, 456

The list of prime factors of all numbers are

Prime factors of 221 are 13 x 17

Prime factors of 851 are 23 x 37

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Given numbers are 221, 851, 400, 456

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

Apply this formula for all numbers.

Step1:

LCM(221, 851) = 188071

GCD(221, 851) = ( 221 x 851 ) / 188071

= 221 / 851

= 221

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

So, Greatest Common Divisor of 221, 851, 400, 456 is 1
