Given numbers are 640, 465, 811, 539

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 465 are 3 x 5 x 31

Prime factors of 811 are 811

Prime factors of 539 are 7 x 7 x 11

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

Given numbers are 640, 465, 811, 539

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

Apply this formula for all numbers.

Step1:

LCM(640, 465) = 59520

GCD(640, 465) = ( 640 x 465 ) / 59520

= 640 / 465

= 640

Step2:

LCM(5, 811) = 4055

GCD(5, 811) = ( 5 x 811 ) / 4055

= 5 / 811

= 5

Step3:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

So, Greatest Common Divisor of 640, 465, 811, 539 is 1
