Given numbers are 411, 405, 404, 749
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(411, 405) = 55485
GCD(411, 405) = ( 411 x 405 ) / 55485
= 411 / 405
= 411
Step2:
LCM(3, 404) = 1212
GCD(3, 404) = ( 3 x 404 ) / 1212
= 3 / 404
= 3
Step3:
LCM(1, 749) = 749
GCD(1, 749) = ( 1 x 749 ) / 749
= 1 / 749
= 1
So, Greatest Common Divisor of 411, 405, 404, 749 is 1
