Given numbers are 821, 830, 159, 324

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 830 are 2 x 5 x 83

Prime factors of 159 are 3 x 53

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 821, 830, 159, 324

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

Apply this formula for all numbers.

Step1:

LCM(821, 830) = 681430

GCD(821, 830) = ( 821 x 830 ) / 681430

= 821 / 830

= 821

Step2:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

Step3:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

So, Greatest Common Divisor of 821, 830, 159, 324 is 1
