Given numbers are 778, 415, 940, 392

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 415 are 5 x 83

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 778, 415, 940, 392

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

Apply this formula for all numbers.

Step1:

LCM(778, 415) = 322870

GCD(778, 415) = ( 778 x 415 ) / 322870

= 778 / 415

= 778

Step2:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 778, 415, 940, 392 is 1
