Given numbers are 450, 434, 645, 371

The list of prime factors of all numbers are

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 434 are 2 x 7 x 31

Prime factors of 645 are 3 x 5 x 43

Prime factors of 371 are 7 x 53

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

Given numbers are 450, 434, 645, 371

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

Apply this formula for all numbers.

Step1:

LCM(450, 434) = 97650

GCD(450, 434) = ( 450 x 434 ) / 97650

= 450 / 434

= 450

Step2:

LCM(2, 645) = 1290

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

= 2 / 645

= 2

Step3:

LCM(1, 371) = 371

GCD(1, 371) = ( 1 x 371 ) / 371

= 1 / 371

= 1

So, Greatest Common Divisor of 450, 434, 645, 371 is 1
