Given numbers are 781, 451, 487, 353

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

Apply this formula for all numbers.

Step1:

LCM(781, 451) = 32021

GCD(781, 451) = ( 781 x 451 ) / 32021

= 781 / 451

= 781

Step2:

LCM(11, 487) = 5357

GCD(11, 487) = ( 11 x 487 ) / 5357

= 11 / 487

= 11

Step3:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

So, Greatest Common Divisor of 781, 451, 487, 353 is 1
