Given numbers are 290, 385, 433, 644

The list of prime factors of all numbers are

Prime factors of 290 are 2 x 5 x 29

Prime factors of 385 are 5 x 7 x 11

Prime factors of 433 are 433

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 290, 385, 433, 644

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

Apply this formula for all numbers.

Step1:

LCM(290, 385) = 22330

GCD(290, 385) = ( 290 x 385 ) / 22330

= 290 / 385

= 290

Step2:

LCM(5, 433) = 2165

GCD(5, 433) = ( 5 x 433 ) / 2165

= 5 / 433

= 5

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 290, 385, 433, 644 is 1
