Given numbers are 645, 364, 463, 778

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 463 are 463

Prime factors of 778 are 2 x 389

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

Given numbers are 645, 364, 463, 778

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

Apply this formula for all numbers.

Step1:

LCM(645, 364) = 234780

GCD(645, 364) = ( 645 x 364 ) / 234780

= 645 / 364

= 645

Step2:

LCM(1, 463) = 463

GCD(1, 463) = ( 1 x 463 ) / 463

= 1 / 463

= 1

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 645, 364, 463, 778 is 1
