Given numbers are 231, 204, 89, 647

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

Apply this formula for all numbers.

Step1:

LCM(231, 204) = 15708

GCD(231, 204) = ( 231 x 204 ) / 15708

= 231 / 204

= 231

Step2:

LCM(3, 89) = 267

GCD(3, 89) = ( 3 x 89 ) / 267

= 3 / 89

= 3

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 231, 204, 89, 647 is 1
