Given numbers are 489, 669, 875, 989

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

Apply this formula for all numbers.

Step1:

LCM(489, 669) = 109047

GCD(489, 669) = ( 489 x 669 ) / 109047

= 489 / 669

= 489

Step2:

LCM(3, 875) = 2625

GCD(3, 875) = ( 3 x 875 ) / 2625

= 3 / 875

= 3

Step3:

LCM(1, 989) = 989

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

= 1 / 989

= 1

So, Greatest Common Divisor of 489, 669, 875, 989 is 1
