Given numbers are 130, 358, 89, 990

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 358 are 2 x 179

Prime factors of 89 are 89

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

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

Given numbers are 130, 358, 89, 990

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

Apply this formula for all numbers.

Step1:

LCM(130, 358) = 23270

GCD(130, 358) = ( 130 x 358 ) / 23270

= 130 / 358

= 130

Step2:

LCM(2, 89) = 178

GCD(2, 89) = ( 2 x 89 ) / 178

= 2 / 89

= 2

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 130, 358, 89, 990 is 1
