Given numbers are 805, 436, 665, 311

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

Apply this formula for all numbers.

Step1:

LCM(805, 436) = 350980

GCD(805, 436) = ( 805 x 436 ) / 350980

= 805 / 436

= 805

Step2:

LCM(1, 665) = 665

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

= 1 / 665

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 805, 436, 665, 311 is 1
