Given numbers are 554, 764, 146, 645

The list of prime factors of all numbers are

Prime factors of 554 are 2 x 277

Prime factors of 764 are 2 x 2 x 191

Prime factors of 146 are 2 x 73

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 554, 764, 146, 645

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

Apply this formula for all numbers.

Step1:

LCM(554, 764) = 211628

GCD(554, 764) = ( 554 x 764 ) / 211628

= 554 / 764

= 554

Step2:

LCM(2, 146) = 146

GCD(2, 146) = ( 2 x 146 ) / 146

= 2 / 146

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 554, 764, 146, 645 is 1
