Given numbers are 490, 912, 689, 989

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 689 are 13 x 53

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 490, 912, 689, 989

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

Apply this formula for all numbers.

Step1:

LCM(490, 912) = 223440

GCD(490, 912) = ( 490 x 912 ) / 223440

= 490 / 912

= 490

Step2:

LCM(2, 689) = 1378

GCD(2, 689) = ( 2 x 689 ) / 1378

= 2 / 689

= 2

Step3:

LCM(1, 989) = 989

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

= 1 / 989

= 1

So, Greatest Common Divisor of 490, 912, 689, 989 is 1
