Given numbers are 721, 439, 944, 505

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

Apply this formula for all numbers.

Step1:

LCM(721, 439) = 316519

GCD(721, 439) = ( 721 x 439 ) / 316519

= 721 / 439

= 721

Step2:

LCM(1, 944) = 944

GCD(1, 944) = ( 1 x 944 ) / 944

= 1 / 944

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 721, 439, 944, 505 is 1
