Given numbers are 644, 720, 886, 256

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

Apply this formula for all numbers.

Step1:

LCM(644, 720) = 115920

GCD(644, 720) = ( 644 x 720 ) / 115920

= 644 / 720

= 644

Step2:

LCM(4, 886) = 1772

GCD(4, 886) = ( 4 x 886 ) / 1772

= 4 / 886

= 4

Step3:

LCM(2, 256) = 256

GCD(2, 256) = ( 2 x 256 ) / 256

= 2 / 256

= 2

So, Greatest Common Divisor of 644, 720, 886, 256 is 2
