Given numbers are 138, 423, 815, 527

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 423 are 3 x 3 x 47

Prime factors of 815 are 5 x 163

Prime factors of 527 are 17 x 31

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

Given numbers are 138, 423, 815, 527

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

Apply this formula for all numbers.

Step1:

LCM(138, 423) = 19458

GCD(138, 423) = ( 138 x 423 ) / 19458

= 138 / 423

= 138

Step2:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

Step3:

LCM(1, 527) = 527

GCD(1, 527) = ( 1 x 527 ) / 527

= 1 / 527

= 1

So, Greatest Common Divisor of 138, 423, 815, 527 is 1
