Given numbers are 645, 760, 432, 404

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 645, 760, 432, 404

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

Apply this formula for all numbers.

Step1:

LCM(645, 760) = 98040

GCD(645, 760) = ( 645 x 760 ) / 98040

= 645 / 760

= 645

Step2:

LCM(5, 432) = 2160

GCD(5, 432) = ( 5 x 432 ) / 2160

= 5 / 432

= 5

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 645, 760, 432, 404 is 1
