Given numbers are 640, 234, 65, 432

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 234 are 2 x 3 x 3 x 13

Prime factors of 65 are 5 x 13

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

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

Given numbers are 640, 234, 65, 432

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

Apply this formula for all numbers.

Step1:

LCM(640, 234) = 74880

GCD(640, 234) = ( 640 x 234 ) / 74880

= 640 / 234

= 640

Step2:

LCM(2, 65) = 130

GCD(2, 65) = ( 2 x 65 ) / 130

= 2 / 65

= 2

Step3:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

So, Greatest Common Divisor of 640, 234, 65, 432 is 1
