Given numbers are 781, 433, 390, 893

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

Apply this formula for all numbers.

Step1:

LCM(781, 433) = 338173

GCD(781, 433) = ( 781 x 433 ) / 338173

= 781 / 433

= 781

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 893) = 893

GCD(1, 893) = ( 1 x 893 ) / 893

= 1 / 893

= 1

So, Greatest Common Divisor of 781, 433, 390, 893 is 1
