Given numbers are 400, 454, 261, 617

The list of prime factors of all numbers are

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

Prime factors of 454 are 2 x 227

Prime factors of 261 are 3 x 3 x 29

Prime factors of 617 are 617

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

Given numbers are 400, 454, 261, 617

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

Apply this formula for all numbers.

Step1:

LCM(400, 454) = 90800

GCD(400, 454) = ( 400 x 454 ) / 90800

= 400 / 454

= 400

Step2:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

Step3:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

So, Greatest Common Divisor of 400, 454, 261, 617 is 1
