Given numbers are 640, 864, 423, 717

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

Apply this formula for all numbers.

Step1:

LCM(640, 864) = 17280

GCD(640, 864) = ( 640 x 864 ) / 17280

= 640 / 864

= 640

Step2:

LCM(32, 423) = 13536

GCD(32, 423) = ( 32 x 423 ) / 13536

= 32 / 423

= 32

Step3:

LCM(1, 717) = 717

GCD(1, 717) = ( 1 x 717 ) / 717

= 1 / 717

= 1

So, Greatest Common Divisor of 640, 864, 423, 717 is 1
