Given numbers are 138, 545, 556, 906

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 545 are 5 x 109

Prime factors of 556 are 2 x 2 x 139

Prime factors of 906 are 2 x 3 x 151

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

Given numbers are 138, 545, 556, 906

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

Apply this formula for all numbers.

Step1:

LCM(138, 545) = 75210

GCD(138, 545) = ( 138 x 545 ) / 75210

= 138 / 545

= 138

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 138, 545, 556, 906 is 1
