Given numbers are 475, 513, 16, 391

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

Apply this formula for all numbers.

Step1:

LCM(475, 513) = 12825

GCD(475, 513) = ( 475 x 513 ) / 12825

= 475 / 513

= 475

Step2:

LCM(19, 16) = 304

GCD(19, 16) = ( 19 x 16 ) / 304

= 19 / 16

= 19

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 475, 513, 16, 391 is 1
