Given numbers are 435, 312, 820, 813

The list of prime factors of all numbers are

Prime factors of 435 are 3 x 5 x 29

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Prime factors of 813 are 3 x 271

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

Given numbers are 435, 312, 820, 813

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

Apply this formula for all numbers.

Step1:

LCM(435, 312) = 45240

GCD(435, 312) = ( 435 x 312 ) / 45240

= 435 / 312

= 435

Step2:

LCM(3, 820) = 2460

GCD(3, 820) = ( 3 x 820 ) / 2460

= 3 / 820

= 3

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 435, 312, 820, 813 is 1
