Given numbers are 456, 208, 406, 581

The list of prime factors of all numbers are

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

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 406 are 2 x 7 x 29

Prime factors of 581 are 7 x 83

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

Given numbers are 456, 208, 406, 581

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

Apply this formula for all numbers.

Step1:

LCM(456, 208) = 11856

GCD(456, 208) = ( 456 x 208 ) / 11856

= 456 / 208

= 456

Step2:

LCM(8, 406) = 1624

GCD(8, 406) = ( 8 x 406 ) / 1624

= 8 / 406

= 8

Step3:

LCM(2, 581) = 1162

GCD(2, 581) = ( 2 x 581 ) / 1162

= 2 / 581

= 2

So, Greatest Common Divisor of 456, 208, 406, 581 is 1
