Given numbers are 838, 138, 462, 515

The list of prime factors of all numbers are

Prime factors of 838 are 2 x 419

Prime factors of 138 are 2 x 3 x 23

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 515 are 5 x 103

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

Given numbers are 838, 138, 462, 515

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

Apply this formula for all numbers.

Step1:

LCM(838, 138) = 57822

GCD(838, 138) = ( 838 x 138 ) / 57822

= 838 / 138

= 838

Step2:

LCM(2, 462) = 462

GCD(2, 462) = ( 2 x 462 ) / 462

= 2 / 462

= 2

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 838, 138, 462, 515 is 1
