Given numbers are 815, 130, 438, 566

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 130 are 2 x 5 x 13

Prime factors of 438 are 2 x 3 x 73

Prime factors of 566 are 2 x 283

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

Given numbers are 815, 130, 438, 566

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

Apply this formula for all numbers.

Step1:

LCM(815, 130) = 21190

GCD(815, 130) = ( 815 x 130 ) / 21190

= 815 / 130

= 815

Step2:

LCM(5, 438) = 2190

GCD(5, 438) = ( 5 x 438 ) / 2190

= 5 / 438

= 5

Step3:

LCM(1, 566) = 566

GCD(1, 566) = ( 1 x 566 ) / 566

= 1 / 566

= 1

So, Greatest Common Divisor of 815, 130, 438, 566 is 1
