Given numbers are 843, 990, 815, 372

The list of prime factors of all numbers are

Prime factors of 843 are 3 x 281

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 815 are 5 x 163

Prime factors of 372 are 2 x 2 x 3 x 31

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

Given numbers are 843, 990, 815, 372

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

Apply this formula for all numbers.

Step1:

LCM(843, 990) = 278190

GCD(843, 990) = ( 843 x 990 ) / 278190

= 843 / 990

= 843

Step2:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

Step3:

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

= 1 / 372

= 1

So, Greatest Common Divisor of 843, 990, 815, 372 is 1
