Given numbers are 644, 758, 394, 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, 758) = 244076

GCD(644, 758) = ( 644 x 758 ) / 244076

= 644 / 758

= 644

Step2:

LCM(2, 394) = 394

GCD(2, 394) = ( 2 x 394 ) / 394

= 2 / 394

= 2

Step3:

LCM(2, 293) = 586

GCD(2, 293) = ( 2 x 293 ) / 586

= 2 / 293

= 2

So, Greatest Common Divisor of 644, 758, 394, 293 is 1
