Given numbers are 640, 706, 688, 585

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 706 are 2 x 353

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 585 are 3 x 3 x 5 x 13

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

Given numbers are 640, 706, 688, 585

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

Apply this formula for all numbers.

Step1:

LCM(640, 706) = 225920

GCD(640, 706) = ( 640 x 706 ) / 225920

= 640 / 706

= 640

Step2:

LCM(2, 688) = 688

GCD(2, 688) = ( 2 x 688 ) / 688

= 2 / 688

= 2

Step3:

LCM(2, 585) = 1170

GCD(2, 585) = ( 2 x 585 ) / 1170

= 2 / 585

= 2

So, Greatest Common Divisor of 640, 706, 688, 585 is 1
