Given numbers are 138, 635, 488, 820

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 635 are 5 x 127

Prime factors of 488 are 2 x 2 x 2 x 61

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 138, 635, 488, 820

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

Apply this formula for all numbers.

Step1:

LCM(138, 635) = 87630

GCD(138, 635) = ( 138 x 635 ) / 87630

= 138 / 635

= 138

Step2:

LCM(1, 488) = 488

GCD(1, 488) = ( 1 x 488 ) / 488

= 1 / 488

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 138, 635, 488, 820 is 1
