Given numbers are 872, 278, 763, 403

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

Apply this formula for all numbers.

Step1:

LCM(872, 278) = 121208

GCD(872, 278) = ( 872 x 278 ) / 121208

= 872 / 278

= 872

Step2:

LCM(2, 763) = 1526

GCD(2, 763) = ( 2 x 763 ) / 1526

= 2 / 763

= 2

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 872, 278, 763, 403 is 1
