Given numbers are 388, 735, 781, 440

The list of prime factors of all numbers are

Prime factors of 388 are 2 x 2 x 97

Prime factors of 735 are 3 x 5 x 7 x 7

Prime factors of 781 are 11 x 71

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 388, 735, 781, 440

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

Apply this formula for all numbers.

Step1:

LCM(388, 735) = 285180

GCD(388, 735) = ( 388 x 735 ) / 285180

= 388 / 735

= 388

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 388, 735, 781, 440 is 1
