Given numbers are 990, 978, 259, 989

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 978 are 2 x 3 x 163

Prime factors of 259 are 7 x 37

Prime factors of 989 are 23 x 43

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

Given numbers are 990, 978, 259, 989

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

Apply this formula for all numbers.

Step1:

LCM(990, 978) = 161370

GCD(990, 978) = ( 990 x 978 ) / 161370

= 990 / 978

= 990

Step2:

LCM(6, 259) = 1554

GCD(6, 259) = ( 6 x 259 ) / 1554

= 6 / 259

= 6

Step3:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

So, Greatest Common Divisor of 990, 978, 259, 989 is 1
