Given numbers are 273, 753, 257, 721

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

Apply this formula for all numbers.

Step1:

LCM(273, 753) = 68523

GCD(273, 753) = ( 273 x 753 ) / 68523

= 273 / 753

= 273

Step2:

LCM(3, 257) = 771

GCD(3, 257) = ( 3 x 257 ) / 771

= 3 / 257

= 3

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 273, 753, 257, 721 is 1
