Given numbers are 665, 911, 436, 256

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

Apply this formula for all numbers.

Step1:

LCM(665, 911) = 605815

GCD(665, 911) = ( 665 x 911 ) / 605815

= 665 / 911

= 665

Step2:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 665, 911, 436, 256 is 1
