Given numbers are 406, 872, 255, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 872) = 177016
GCD(406, 872) = ( 406 x 872 ) / 177016
= 406 / 872
= 406
Step2:
LCM(2, 255) = 510
GCD(2, 255) = ( 2 x 255 ) / 510
= 2 / 255
= 2
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 406, 872, 255, 805 is 1
