Given numbers are 384, 639, 640, 803

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

Apply this formula for all numbers.

Step1:

LCM(384, 639) = 81792

GCD(384, 639) = ( 384 x 639 ) / 81792

= 384 / 639

= 384

Step2:

LCM(3, 640) = 1920

GCD(3, 640) = ( 3 x 640 ) / 1920

= 3 / 640

= 3

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 384, 639, 640, 803 is 1
