Given numbers are 138, 715, 816, 554

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 715 are 5 x 11 x 13

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 554 are 2 x 277

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

Given numbers are 138, 715, 816, 554

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

Apply this formula for all numbers.

Step1:

LCM(138, 715) = 98670

GCD(138, 715) = ( 138 x 715 ) / 98670

= 138 / 715

= 138

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 138, 715, 816, 554 is 1
