Given numbers are 868, 415, 665, 865

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

Apply this formula for all numbers.

Step1:

LCM(868, 415) = 360220

GCD(868, 415) = ( 868 x 415 ) / 360220

= 868 / 415

= 868

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 868, 415, 665, 865 is 1
