Given numbers are 973, 387, 530, 180

The list of prime factors of all numbers are

Prime factors of 973 are 7 x 139

Prime factors of 387 are 3 x 3 x 43

Prime factors of 530 are 2 x 5 x 53

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 973, 387, 530, 180

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

Apply this formula for all numbers.

Step1:

LCM(973, 387) = 376551

GCD(973, 387) = ( 973 x 387 ) / 376551

= 973 / 387

= 973

Step2:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 973, 387, 530, 180 is 1
