Given numbers are 640, 911, 521

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 911 are 911

Prime factors of 521 are 521

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

Given numbers are 640, 911, 521

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

Apply this formula for all numbers.

Step1:

LCM(640, 911) = 583040

GCD(640, 911) = ( 640 x 911 ) / 583040

= 640 / 911

= 640

Step2:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 640, 911, 521 is 1
