Given numbers are 644, 494, 796, 755

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

Apply this formula for all numbers.

Step1:

LCM(644, 494) = 159068

GCD(644, 494) = ( 644 x 494 ) / 159068

= 644 / 494

= 644

Step2:

LCM(2, 796) = 796

GCD(2, 796) = ( 2 x 796 ) / 796

= 2 / 796

= 2

Step3:

LCM(2, 755) = 1510

GCD(2, 755) = ( 2 x 755 ) / 1510

= 2 / 755

= 2

So, Greatest Common Divisor of 644, 494, 796, 755 is 1
