Given numbers are 530, 812, 845, 147

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 845 are 5 x 13 x 13

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 530, 812, 845, 147

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

Apply this formula for all numbers.

Step1:

LCM(530, 812) = 215180

GCD(530, 812) = ( 530 x 812 ) / 215180

= 530 / 812

= 530

Step2:

LCM(2, 845) = 1690

GCD(2, 845) = ( 2 x 845 ) / 1690

= 2 / 845

= 2

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 530, 812, 845, 147 is 1
