Given numbers are 646, 455, 436, 433

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 455 are 5 x 7 x 13

Prime factors of 436 are 2 x 2 x 109

Prime factors of 433 are 433

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

Given numbers are 646, 455, 436, 433

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

Apply this formula for all numbers.

Step1:

LCM(646, 455) = 293930

GCD(646, 455) = ( 646 x 455 ) / 293930

= 646 / 455

= 646

Step2:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

Step3:

LCM(1, 433) = 433

GCD(1, 433) = ( 1 x 433 ) / 433

= 1 / 433

= 1

So, Greatest Common Divisor of 646, 455, 436, 433 is 1
