Given numbers are 189, 477, 64, 448

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

Apply this formula for all numbers.

Step1:

LCM(189, 477) = 10017

GCD(189, 477) = ( 189 x 477 ) / 10017

= 189 / 477

= 189

Step2:

LCM(9, 64) = 576

GCD(9, 64) = ( 9 x 64 ) / 576

= 9 / 64

= 9

Step3:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

So, Greatest Common Divisor of 189, 477, 64, 448 is 1
