Given numbers are 781, 198, 479, 472

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

Apply this formula for all numbers.

Step1:

LCM(781, 198) = 14058

GCD(781, 198) = ( 781 x 198 ) / 14058

= 781 / 198

= 781

Step2:

LCM(11, 479) = 5269

GCD(11, 479) = ( 11 x 479 ) / 5269

= 11 / 479

= 11

Step3:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

So, Greatest Common Divisor of 781, 198, 479, 472 is 1
