Given numbers are 803, 729, 781, 853

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

Apply this formula for all numbers.

Step1:

LCM(803, 729) = 585387

GCD(803, 729) = ( 803 x 729 ) / 585387

= 803 / 729

= 803

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 803, 729, 781, 853 is 1
