Given numbers are 783, 240, 439, 478

The list of prime factors of all numbers are

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 439 are 439

Prime factors of 478 are 2 x 239

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

Given numbers are 783, 240, 439, 478

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

Apply this formula for all numbers.

Step1:

LCM(783, 240) = 62640

GCD(783, 240) = ( 783 x 240 ) / 62640

= 783 / 240

= 783

Step2:

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

= 3 / 439

= 3

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 783, 240, 439, 478 is 1
