Given numbers are 820, 530, 921, 858

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 530 are 2 x 5 x 53

Prime factors of 921 are 3 x 307

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 820, 530, 921, 858

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

Apply this formula for all numbers.

Step1:

LCM(820, 530) = 43460

GCD(820, 530) = ( 820 x 530 ) / 43460

= 820 / 530

= 820

Step2:

LCM(10, 921) = 9210

GCD(10, 921) = ( 10 x 921 ) / 9210

= 10 / 921

= 10

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 820, 530, 921, 858 is 1
