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
