Given numbers are 645, 413, 746, 385

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 413 are 7 x 59

Prime factors of 746 are 2 x 373

Prime factors of 385 are 5 x 7 x 11

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

Given numbers are 645, 413, 746, 385

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

Apply this formula for all numbers.

Step1:

LCM(645, 413) = 266385

GCD(645, 413) = ( 645 x 413 ) / 266385

= 645 / 413

= 645

Step2:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 645, 413, 746, 385 is 1
