Given numbers are 138, 145, 249, 826

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 145 are 5 x 29

Prime factors of 249 are 3 x 83

Prime factors of 826 are 2 x 7 x 59

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

Given numbers are 138, 145, 249, 826

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

Apply this formula for all numbers.

Step1:

LCM(138, 145) = 20010

GCD(138, 145) = ( 138 x 145 ) / 20010

= 138 / 145

= 138

Step2:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

Step3:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1

So, Greatest Common Divisor of 138, 145, 249, 826 is 1
