Given numbers are 640, 570, 775, 571

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 570 are 2 x 3 x 5 x 19

Prime factors of 775 are 5 x 5 x 31

Prime factors of 571 are 571

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

Given numbers are 640, 570, 775, 571

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

Apply this formula for all numbers.

Step1:

LCM(640, 570) = 36480

GCD(640, 570) = ( 640 x 570 ) / 36480

= 640 / 570

= 640

Step2:

LCM(10, 775) = 1550

GCD(10, 775) = ( 10 x 775 ) / 1550

= 10 / 775

= 10

Step3:

LCM(5, 571) = 2855

GCD(5, 571) = ( 5 x 571 ) / 2855

= 5 / 571

= 5

So, Greatest Common Divisor of 640, 570, 775, 571 is 1
