Given numbers are 644, 263, 426, 293

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

Apply this formula for all numbers.

Step1:

LCM(644, 263) = 169372

GCD(644, 263) = ( 644 x 263 ) / 169372

= 644 / 263

= 644

Step2:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

Step3:

LCM(1, 293) = 293

GCD(1, 293) = ( 1 x 293 ) / 293

= 1 / 293

= 1

So, Greatest Common Divisor of 644, 263, 426, 293 is 1
