Given numbers are 319, 891, 821, 917

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

Apply this formula for all numbers.

Step1:

LCM(319, 891) = 25839

GCD(319, 891) = ( 319 x 891 ) / 25839

= 319 / 891

= 319

Step2:

LCM(11, 821) = 9031

GCD(11, 821) = ( 11 x 821 ) / 9031

= 11 / 821

= 11

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 319, 891, 821, 917 is 1
