Given numbers are 530, 689, 819, 140

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 689 are 13 x 53

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 530, 689, 819, 140

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

Apply this formula for all numbers.

Step1:

LCM(530, 689) = 6890

GCD(530, 689) = ( 530 x 689 ) / 6890

= 530 / 689

= 530

Step2:

LCM(53, 819) = 43407

GCD(53, 819) = ( 53 x 819 ) / 43407

= 53 / 819

= 53

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 530, 689, 819, 140 is 1
