Given numbers are 645, 778, 124, 384

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 778 are 2 x 389

Prime factors of 124 are 2 x 2 x 31

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 645, 778, 124, 384

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

Apply this formula for all numbers.

Step1:

LCM(645, 778) = 501810

GCD(645, 778) = ( 645 x 778 ) / 501810

= 645 / 778

= 645

Step2:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

Step3:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

So, Greatest Common Divisor of 645, 778, 124, 384 is 1
