Given numbers are 640, 128, 505, 272

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

Apply this formula for all numbers.

Step1:

LCM(640, 128) = 640

GCD(640, 128) = ( 640 x 128 ) / 640

= 640 / 128

= 640

Step2:

LCM(128, 505) = 64640

GCD(128, 505) = ( 128 x 505 ) / 64640

= 128 / 505

= 128

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 640, 128, 505, 272 is 1
