Given numbers are 990, 381, 13, 702

The list of prime factors of all numbers are

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

Prime factors of 381 are 3 x 127

Prime factors of 13 are 13

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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

Given numbers are 990, 381, 13, 702

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

Apply this formula for all numbers.

Step1:

LCM(990, 381) = 125730

GCD(990, 381) = ( 990 x 381 ) / 125730

= 990 / 381

= 990

Step2:

LCM(3, 13) = 39

GCD(3, 13) = ( 3 x 13 ) / 39

= 3 / 13

= 3

Step3:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

So, Greatest Common Divisor of 990, 381, 13, 702 is 1
