Given numbers are 815, 708, 290, 456

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 708 are 2 x 2 x 3 x 59

Prime factors of 290 are 2 x 5 x 29

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 815, 708, 290, 456

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

Apply this formula for all numbers.

Step1:

LCM(815, 708) = 577020

GCD(815, 708) = ( 815 x 708 ) / 577020

= 815 / 708

= 815

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

Step3:

LCM(1, 456) = 456

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

= 1 / 456

= 1

So, Greatest Common Divisor of 815, 708, 290, 456 is 1
