Given numbers are 157, 519, 138, 660

The list of prime factors of all numbers are

Prime factors of 157 are 157

Prime factors of 519 are 3 x 173

Prime factors of 138 are 2 x 3 x 23

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 157, 519, 138, 660

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

Apply this formula for all numbers.

Step1:

LCM(157, 519) = 81483

GCD(157, 519) = ( 157 x 519 ) / 81483

= 157 / 519

= 157

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 157, 519, 138, 660 is 1
