Given numbers are 663, 284, 526, 989

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

Apply this formula for all numbers.

Step1:

LCM(663, 284) = 188292

GCD(663, 284) = ( 663 x 284 ) / 188292

= 663 / 284

= 663

Step2:

LCM(1, 526) = 526

GCD(1, 526) = ( 1 x 526 ) / 526

= 1 / 526

= 1

Step3:

LCM(1, 989) = 989

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

= 1 / 989

= 1

So, Greatest Common Divisor of 663, 284, 526, 989 is 1
