Given numbers are 138, 407, 124, 521

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 407 are 11 x 37

Prime factors of 124 are 2 x 2 x 31

Prime factors of 521 are 521

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

Given numbers are 138, 407, 124, 521

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

Apply this formula for all numbers.

Step1:

LCM(138, 407) = 56166

GCD(138, 407) = ( 138 x 407 ) / 56166

= 138 / 407

= 138

Step2:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

Step3:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 138, 407, 124, 521 is 1
