Given numbers are 253, 165, 917, 868

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

Apply this formula for all numbers.

Step1:

LCM(253, 165) = 3795

GCD(253, 165) = ( 253 x 165 ) / 3795

= 253 / 165

= 253

Step2:

LCM(11, 917) = 10087

GCD(11, 917) = ( 11 x 917 ) / 10087

= 11 / 917

= 11

Step3:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

So, Greatest Common Divisor of 253, 165, 917, 868 is 1
