Given numbers are 781, 132, 393, 493

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 132 are 2 x 2 x 3 x 11

Prime factors of 393 are 3 x 131

Prime factors of 493 are 17 x 29

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 781, 132, 393, 493

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

Apply this formula for all numbers.

Step1:

LCM(781, 132) = 9372

GCD(781, 132) = ( 781 x 132 ) / 9372

= 781 / 132

= 781

Step2:

LCM(11, 393) = 4323

GCD(11, 393) = ( 11 x 393 ) / 4323

= 11 / 393

= 11

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 781, 132, 393, 493 is 1
